I'm not familiar with the OPC-420. Is it the cable with a 4-pin connector on one end and no connector on the other?

They're definitely firm. It's a short bed, so it's rough anyway. The flipside is that it handles well and the steering feels confident.

I'm not sure. I would say at least 700 wheel. There are people that have gone a long way on a stock parts.

The 2017 Escalade should be the same as in the video. Look under the truck for the plug.

@@n5yiz will it need programming?

No, just made it up. It's just a simple dipole.

I plan on going down the 160 "rabbit hole" next winter. I'll be working on a full-wave loop towards the end of the summer.

Correction: The Kicker 10s were 12 years old! I originally had them in my 2012 Silverado. Kicker makes really good speakers!

You can adjust the 20m version down to get the higher bands. I just use the quarter wave formula to get it close and then fine adjust from there. Use a Sharpie to mark the tubes for different band configs. It's going to be a couple months, but I'll be installing the 20m and 40m permanently on a Rohn mast. I'll try to video as much as I can.

@@n5yiz so bringing in the elements brings it from 20 down to what meter band you want? I’m learning as I go.

Those are 10 gauge, made from Silicone wire from Amazon. I only used them briefly in that configuration. Unable to determine if they made any difference.

thanks...have fun tomorrow

The antenna in the video is a Tram 1115-B. I don't think there are many options for NMO mountable CB antennas. The Larsen NMO27 will work for CB use, but you need to check you bandwidth requirements.

@@n5yiz Thank You!!

The pigtail I used is just a simple common mode choke. The center pin of the coax goes to one side of the dipole and the shield (braid) is attached to the other. It sounds like you may have a short if you wrapped your own. Check for continuity through the choke for both the center conductor and braid with a multimeter. I'm not sure if you were stating a sweep of the dipole with your Unun resulted in the lowest SWR at 21mhz or your were targeting 21mhz. The specs for the one in the video is for 14mhz (20m). Sorry, it's hard to gauge someones technical knowledge through the comment section. As a quick test, I think it would be best to bypass the choke or unun entirely. Just connect your feedline directly to each leg of the dipole. Sweep or check the SWR. I'm working on an update video about a 40m rotatable I made a few months back. I'll try to explain the feedpoint a little better. Video should be out Monday if you don't get is solved until then. Good Luck!

@@n5yiz you were spot on. The continuity on the coax was non-existent on the center wire. Seems I was using too large of a wire lug. 73s and many thanks.

That's going to be incredible. If you have the tower to support the weight, you'll have no problem getting to the required length startng with 3" tube. I used 1.25" primary and worked down to a 3/8 tube and that got me to 32.5' easy. It droops without the support truss, but it's not even close to collapsing under it's own weight. Using a 3" primary you have a lot of headroom to get to 100 feet. I honestly just finished drilling and bolting the tubes for the 40m last week. I plan on using it during field day. I did change a couple of things since I made that video. I'll make another showing the revisions.

@@n5yiz looking forward to the update video! My project will be a slow moving one because first I will have to get a tower up that high. I already have plenty of tower. I just need an approved place to put it and the time!

Maybe they thought the SO-239 center sleeve might get loose over time? I thought about soldering the VHF N socket, but decided against in case of warranty work.

Now that I think about it, the center pin of the N connector is not really engaged until the outer sleeve is threaded on. No so with the PL259/SO239. You can put leverage on the SO239 center sleeve by just inserting the PL259 center pin half way or so. Interesting.

I just tried to find my pics from the last time I had the 7100 open to make sure I'm remembering correctly, but no joy, I'll have to remember next time I'm in there 😂 Both my ANT ports are the SO239's that it came with but I've thought about making the N connector change too, at least for UHF!

To me, amphenol or other quality brand is worth it. The 9700 is a great radio. I have one. I tried cheap connectors, they lose contact or even raise VSWR. Connectors can be specified as 50, 75, or non specific. There is a physical difference. My Tektronix TTR506 can measure the difference. The meter on the 9700 may or may not. But if performance matters, spend $14, and know what you are getting.

Power input is certainly a limitation.

It's easy to build...good luck

Bryan...I'll send you an email later with what I have.

I figured it out .

@@brucerobson8284 sorry about the late reply...good you got it sorted out.

Also on the grey connectors, when you connected one end back into the OEM amplifier, does the other end just not get plugged in?

It was a DIY project. There's a build video somewhere on my channel.

They all need to be modified for continuous coverage. The Euro models (the ones with 03 serial number prefix) have 70mhz components that the others don't.

@@n5yiz Thank you

I would hate guess at that one and tell you wrong.

Search "Reebow Gear Military Backpack" on Amazon.

I believe it's about 7 feet in length.

I honestly don't know. Don't want to steer you the wrong way.

It's very hard to say what angle you need. You many not need any. Are you having problems?

Bolts aren't straight turned in

U Bolts aren't straight like yours they're turned in some. I pit extenders on but I have belltech lowering shocks on there now ride isn't great I'm going to change shocks to oem bilsteins B6 4600

@@jasonnellis3566 You mean the four bolts on the leaf springs are canted towards the front?

@n5yiz yes sir the ubolts

I had the Speed Engineering kit on it at that time.

I’m installing a 2.9 supercharger on my 2018 5.3L sierra single cab this week so I’m wondering if the stock exhaust can handle the pressure or not. I have already installed a long tube headers with a Y pipe only. Any additional advices ?
