That’s amazing how easily the ground rod went into the earth. Also surprisingly easy to remove the ground rod from the earth. Never that easy in the clay soil in Texas Panhandle.

[@DarrenN4VFR]

Yeah, I bet that it's harder to remove from clay. A viewer recommended a 10' copper 1/2" tubing and sticking a garden hose with hose clamps to one end and driving it in the earth with the water on. But in clay soil, idk if that will work.

Hi Capt Darren. I have a couple of questions for you if that's OK. What diameter water pipe did you use for your installation and what size clamp did you use to mount the DX Enginnering ground plate to the pipe? Lastly, did you make the radials yourself or did you purchase them pre-made? If you made them yourself, what size wire gauge did you use and what size eye connectors did you use? Thanks for the help and advice! David, K7KDE

[@basspig]

I put up a 92' tall vertical using a drone as a skyrocketing to drop a fishing line over the tallest branch of a tree. The antenna was supported at the top by 3' of vinyl tubing tied to a nylon rope which went to the tie point on the ground. The 14awg copper wire was hanging Straight down and connected to porcelain insulator where it connects to the coax. This antenna worked fantastic. Relative to my horizontal longtime, it typi c ally was 3 to 15db higher signal strength on 75 through 20m than the reference horizontal ant. Due to high winds, the antenna came down after 3 days of phenomenal dx. I decided to ruggedize the improved suspension with 5' of guy wire with ptfe tubing over it so it doesn't chafe on the branch and cut the rope. There is 3 feet of vinyl cord etween the vertical wire and the guy wire, which runs horizontal across branches before going down vertical. Only the top 3 feet of wire are parallel to this steel guy wire 3 feet away. However this ruggedized antenna mount has poor performance. I thought my coax switch was wire backwards because rhe reference ant was outperforming the vertical after the update. I am still trying to get my head wrapped around the fact that 3 feet of steel 3 feet away from. The main radiator would drastically degrade antenna se sitivity.

[@DarrenN4VFR]

Thats awesome you used a drone to put up that wire antenna. Good luck Dxing!

[@basspig]

@@DarrenN4VFR I have a Fli-Fli Airdrop attached to my Phantom 4 Pro 2.0 and what I do is use a nylon cord about 8' long with a loop on one end for attaching to the release pin on the Airdrop and the other end is secured to an empty WD40 can as a weight. Then I attach the leader cord just above the can. The leader is on a spool that unwinds as the drone gains altitude. I fly up over the branch I want to use and out a bit and then hit the drop button and the weight of the can pulls the cord down to a height I can reach and I then tie my nylon rope to the can end of the line and start winding up the spool, pulling the nylon rope up to the top of tree. The other end of the rope is attached to 5' of steel guy with a PTFE sleeve over it, followed by 3' of vinyl cord as insulator and finally the copper wire. Whole operation takes about 5 minutes. Propagation has been peculiar this year. Some days the vertical does poorly, some days it's better. Sometimes I can be listening to a QSO and one station will fade on the horizontal and I switch to vertical and it's up 10dB where 5 minutes ago it was the reverse!

Hey Darren, Scott from BARS. Nice antenna install, you'll have to do a show and tell one day :) Tip for the 101D, turn down the RF gain to around 10 o'clock position and use DNR on that radio, it has outstanding noise reduction to get rid of a bunch of that band noise. 73! Scott N1SER

[@rogerp5816]

Two comments and one question on your installation: 1.) Good to see you use the SS-30 to keep the connections clean and corrosion free. I never knew about the stuff until I started watching Tim Duffy, K3LR from DX Engineering and On All Bands. There was one antenna Tim showed coming down last summer to be replaced that had SS-30 on it for I think twenty years and there was no corrosion at all and the elements came apart easily. 2.) Don't use the flat braid outside where it can absorb water and deteriorate. Again Tim goes over this on a couple of his videos about grounding and bonding. Between the ground rod and the DX Engineering ground plate you should use minimum number six stranded copper wire, you can buy it by the foot at Home Depot. Did you bond the antenna ground rod to the house electrical panel ground with a minimum of number six stranded copper wire? See NEC section 810 for details. You may also want to review Grounding and Bonding by Ward Silver available through the ARRL or DX Engineering. Ward also spoke last year at Contest University and I believe those videos are still on-line. It looks like that antenna can be easily tilted down during a hurricane or other high wind event.

[@DarrenN4VFR]

Thank you for the recommendation. I will replace my antenna ground tomorrow. No, the antenna mast is not grounded to the house service panel. It has it's own grounding rod. My station ground is grounded to the house service panel and also my coax shield from the antenna. And yes, it can tilt down easily for maintenance or for severe storms.

[@douglaswilliams6834]

Capt Darren I received ZF 27' vertical and UNUN (which he seems to outsource from Balun Designs, LLC) last week, and unpacked it today. Everything looks *very* sturdy and high quality. We have a few days of nice weather forecast here in east TN, so I plan to get it installed this week. This is going to be replacing a trapped "WiMo" WARC band vertical that I installed a couple of months ago and haven't been very happy with due to water getting into the trap and throwing the SWR way off. Upon initial examination, the ZeroFive antenna is *far* more sturdy and better constructed. I already have the mounting pipe concreted in the the ground, as well as a DXE radial plate and 8 radials installed, so the ZeroFive antenna should be a drop in replacement for the WiMo. I plan to add more radials, up to at least 30. I'll let you know how it goes. 73 de WB4DW

[@douglaswilliams6834]

Douglas Williams 1 hour ago Got it installed this morning. I was again impressed by the quality of everything about this antenna. Since my main antenna is a Hustler 5BTV, I'll mostly be using the 27' ZeroFive antenna on the WARC bands. I fed it with 50' of LMR-240. The SWR is around 2:1 on 30 and 12 meters, and around 4:1 on 17 meters. The built in ATU in my Kenwood TS-890 is able to tune it to 1:1 SWR on all three bands, which results in a mere 1 dB loss at 18 MHz (0.6 of which is due to the 4:1 SWR), so not worth installing a remote ATU.

[@DarrenN4VFR]

Awesome! You will need a tuner to bring the SWR's down to 1.5. I'm using the Palstar AT2K and tweak my SWRs down to Nil. Let me know how it works! I'm templed to get another one for my dedicated FT8.

John, will do. Right now, my noise floor on 20 and 40 meters is too noisy. I'm thinking about getting a Common Mode Choke. The SWR's straight from the factory using the built in ATU is 1.5 as advertised. When I use my Palstar AT2K Tuner, I can tune the SWR flat, 1:1. Today, I changed out the braided ground to a 6 gauge stranded wire; recommended by one of my viewers. Thanks for commenting!

Aloha Darren, if you can find a copy of the ARRL Technician manual from 10 years ago, they had an aerial shot of the US Coast Guard tower located on the south point of the Big Island of Hawai’i. It’s the same concept of the antenna you just installed. In that aerial photo, you’ll see that there is a highway that runs next to that antenna and it makes the cars as small as ants, it’s simply amazing. You can see the ground radials spread out in a circle but you can’t see them while standing right on top of them. Check it out! If it were me doing the install, I would of dug about 6-8 inches down first and hammered in the galvanized pipe and the ground rod 6-8 inches from the pipe and used a square green plastic irrigation plate and frame for easy access, either flush or elevated, it would of looked very professional. Plus you could of added those 27’ radials about 1-2” down and never have to worry about mowing the lawn or damaging the antenna. I was hoping you would of mentioned in the video the total cost of the antenna and your total costs. I love this antenna design and set up, easy to raise and lower if ever needed, which I doubt you’ll ever have to do. BTW, where did you buy that antenna? This would be a great antenna for my Xiegu G90 also for QRP. 73’

Aloha Braddah Todd! I'm from Oahu and now live in Florida. Thank you for the recommendations and I need to check out that antenna you described about on the Big Island.

I think it was 46 radials? As far as costs, the Antenna System cost $399.00, plus 500' ground radials from DX Engineering $99.00, DX Engineering Ground Plate, $80.00. Total estimate is around $578, not including the cost for Coax and Antiseize (SS-30). Thank you for watching!

Excellent video. I hope the antenna has been working out for you. My only technical comment is that you have used braided ground strap to the ground rod.

Gorgeous installation! It looks like it was done by a professional! It just goes to show that you can get excellent results if you spend the money and get the right components for the job. One question - why not use a hoe and just create a very narrow trench for each of the radials so they’re at least 1/2 to 1” below ground? I’d be worried that running a lawn mower is going to chop up the wires (and probably destroy the lawn mower).

[@douglaswilliams6834]

@steve patterson Steve, this antenna is simply a ground plane vertical that uses the transformer ("UNUN") at the base to help match the impedance since it does not use traps to make it resonant on the various bands it is designed for. It relies on the antenna tuner in your shack to finish matching the impedance so your transceiver does not see a high SWR, but your coax will, so using good quality coax is imperative. It will, of course, work with a couple of ground rods connected at the base of the antenna, but, unless you live in a saltwater swamp, I can guarantee you that you can achieve better performance from this antenna by installing ground radials. The more, the better. Ground radials aren't all that hard to install. There is no need to dig into your lawn. Simply lay them right on the grass and use lawn staples every couple of feet. The grass will grow over and hide them in a matter of weeks. 73 de WB4DW

I operate primarily on 40m on 7178khz. Without a tuner my SWR is > 5.0:1 I don't know why therefore, I use the built in tuner on the FTDX101MP. With 200w barefoot, I get an SWR of 1.5:1. I just received a Palstar AT2K and will try a manual tuner.

[@daveN2MXX]

@@DarrenN4VFR I'm glad it works well for you! Smart choice using good coax- the loss in the coax due to 5:1 mismatch won't be too unreasonable on 40M. Just know that at a 10:1 SWR mismatch (if the tuner is at the transceiver), you will likely lose about 50% of your power in the coax before it reaches the antenna.

@@DarrenN4VFR I would suggest you get an antenna analyzer and check where the antenna is resonant. You may need to adjust the amount the elements are inserted into each other to get your SWR down to a more acceptable level.

Yeah, it's a high noise floor. A technique is to increase the RF Gain so that you eliminate most of the noise to where you only have S1-S2 units displaying. That's what I'm now doing when I got Remote HF Control to my IC7610. Where I live in Florida, there's still so much Power line noise.

[@dariochoa]

Darren, how would you compare the performance of your old cha250b with the new zero five vertical?

[@DarrenN4VFR]

The CHA250b was okay. I hear stations better with the Zero Five antenna. It was just a lot of work to install all the ground radials. I like the fact that the Zero Five antenna can fold over so you can take it down before a hurricane.

[@douglaswilliams6834]

I'm pretty sure the CHA250b uses resistors inside the "matching unit" at the base of the antenna in order to keep SWR low, so a significant portion of your transmit power is wasted heating those resistors.

[@mikemcdonald5147]

does it matter if the radials are insulated or not? Never had an antenna that needed them so i dont know.

[@DarrenN4VFR]

I dont think it would matter just if the bare ground wires are exposed in the elements, it may corrode sooner thank insulated ones.

[@W9HJBill]

Nice install, but I have only one comment. SS-30 is great stuff, but I would not recommend using it on aluminum. Aluminum and copper have too great a galvanic index difference (-0.35 for copper and -0.75 to -0.90 for aluminum ... you really want to only have a 0.15 difference, unless you are in a temperature and humidity controlled environment). I personally would recommend taking the antenna apart, cleaning the SS-30 of and use Penetrox A instead. PS, I love the FTdx-101. 73 W9HJ

[@DarrenN4VFR]

Thank you for the advice. I will definitely do that.

[@douglaswilliams6834]

W9HJ Yet I wonder why DX Engineering always recommends SS-30 for aluminum antenna joins? When I put together my Hustler 5BTV I used GB Ox-Gard, which is basically zinc infused petroleum jelly, between the joins, but that stuff is pretty slick and you really have to tighten the hose clamps to keep the tubes from slipping. When I put together my 27' Zero Five antenna I used the Jet Lube SS-30, just like Capt Darren did. It's a lot thicker than GB Ox-Gard. Hopefully I won't run into problems on down the line. 73 de WB4DW

[@cnick6]

Yes I agree. Anti-seize is for the mounting bolts and clamps whereas Penetrox should be used for preventing oxidation on any antenna elements. I used it also on my radial hardware as well. I own the ZF 10-40 GP and it's still going strong after 12 years.

[@DarrenN4VFR]

After I bought the 27' HOA vertical whip, I called Tom at Zero Five. He recommended to me to have ground radials and therefore, I bought the Ground Radial Plate from DX Engineering. Goto the FAQ page (zerofive-antennas.com/q-and-a/) and you will see the information about ground radials.

[@w4mkh]

@@DarrenN4VFR OK. Thanks for the reply. Still, I wonder why they advertise it sa "no radials". Seems kind of misleading. No doubt though, it will work better with radials.

[@2EOGIY]

9:36 there is an engineering error in the production. no stress release holes. If it is possible then drill holes at the end of cuts with a diameter at least twice the gap. If you do not understand what am I talking about look at how the seat post is mounted into a seat tube. another mistake made is copper grease with aluminum. At first, the grease is insulation, which means capacitive coupling between elements. second copper particles mixed with that grease will corrode the antenna over time - a tight connection is good enough. that cover over the grounding rod is a brilliant idea. You could go further and recess that rod a bit more. Use a wide PVC pipe to prevent soil from sliding over. The purpose for covering it is that when deeper the ground has bigger moisture. The cap will prevent evaporating or allow access to water the rod like a plant.

[@DarrenN4VFR]

Thanks for recommending the stress release holes. I will remove the Jetlube that I used in this video and clean it well and then use Naolox instead.

Why so close to the ground? Mount it to a 10 meter pole. Give it some good height. 😂

[@MrMikesMondoVideo]

You have a few problems with this installation, Unfortunately, a couple of them are rather serious. First, your ground needs to be bonded to the service entrance. All grounds must be bonded. SS-30 Is a Cu paste. This is not appropriate for aluminum. You have unnecessarily introduced two dissimilar metals and this will encourage galvanic corrosion. There are other products that will work, including Noalox. In this case, you would have been better off using nothing at all. DX engineering incorrectly recommends this for aluminum antennas and that is patently wrong. DO NOT USE SS-30 here.

[@DarrenN4VFR]

With regards to grounding. Your saying that the Mast ground must also be bonded to the Station Ground? My Station Ground is bonded to my Service Ground at the house. I thought the mast and station ground had to be seperated. Thank you for the feedback on the SS-30. Frinking DX Engineering recommending that product. I'll look at Noalox.

[@MrMikesMondoVideo]

@@DarrenN4VFR Yes, all grounds must be bonded. The NEC (National Electric Code) will confirm this. Warning: Reading the NEC will make your head explode. :) Rather than a long and boring explanation, check out Mike Holt, here on youtube. He is a great resource for the NEC. JetLube may have an appropriate product for aluminum to aluminum. I have always used Noalox, but there are other suitable products. I don't know why DX Engineering recommends this product. Perhaps it has something to do with the fact that Tim Duffy also owns Summit Racing, and that product has applications there. That's pure speculation. One last thing I probably should mention - There's a law diminishing returns for ground radials. Generally 4 times the lowest band’s wavelength is optimal (balance of work v performance) for the total length of all ground wires. Unlike elevated radials, the actual length is not important as they detune on the ground. It is the total length of the wires that is important... this, of course, is without exaggerating one parameter or another. Nothing wrong with doing more than that. You're just not going to get a lot of dB for the work. Otherwise, nice job and clean work! NB Checkout the Motorola R56 Standard. :)
