More Gain, More Power - 2m S2S Madness

The Arizona Summit-to-Summit 10 Point Madness event provides a great opportunity to push the limits of 2m simplex and see what's possible over long distances. Although I didn't set any new personal records on this trip, some great contacts were made and plenty of fun was had.
The yagi is a homebrew design made from U-channel aluminum, steel hardware, and arrow shaft elements. The matching network is made from parallel 1/4 wavelength sections of 75 ohm coax to transform the 28 ohm yagi impedance up to 50 ohms. Those coax sections are wound a few times through a toroid as a common mode choke.
The boom is about 8 ft in length when extended and folds down to 32 inches. total weight of the antenna is about 2 lbs, and the pool cleaning pole mast adds another 2 lb or so.

Always fun to watch you on the summit. 👍

[@azav8raa]

Great video, Adam. At one point I thought you were going to pull a Honda generator out of the bottom of the pack! Love the 2M yagi, but watching the elements screw on has me pondering different ways to deploy (attach) the elements. When deploying my own portable 2 element 20 - 6 yagi, most of the time is spent screwing it all together. Maybe magnet attached elements that saddle the boom. Nice to see you back. 73.

[@ke6mt]

Nice setup, Adam! I agree - those horned lizards are soooo cute! 73, Rex KE6MT

Fantastic job, you're video production keeps getting better and better! I'm jealous, I don't have any summits nearby, otherwise I'd be out constantly. 73

Have you checked out the ELK 5L logperiodic dual band beam. 9/11 db gain respectively in a 1.5 pound package. I'm surprised how lightweight your beam is. Great stuff.

I am glad we could help you with the 2m AMP we tested at the HARC Test bench. That is a nice 2 meter yagi and it looks like you had fun on 2m!

[@n5pa]

Great video Adam! I am mainly a Contester and DXer, but I enjoy working a new Grid Square on the Weak Signal as much as a new DXCC Entity. I have never operated 2 meter Weak Signal from a mountain top, but I have been in on a lot of great Tropo openings and have 41 states on Tropo. It was exciting watching you work the good 2 meter DX!

[@K6ARK]

Awesome, thank you. Unfortunately, we don't get much tropo out here in Southern California except for the occasional offshore propagation. We do occasionally get openings out to Hawaii even. If I see the propagation forecasts picking up enough for that to be a possibility, you can bet I will be on a local mountain top with my station giving it a try. Thanks again for the kind words, and good dx.

[@n5pa]

@@K6ARK: Adam, hopefully you can get in on a good Tropo opening. They are a blast! One Sunday night in the late 70’s there were several of us on 144.200 with our nightly activity when a guy broke in and asked where we were located. He was in Poughkeepsie, NY. Then for the next hour it was like 20 meters during CQWW. Worked 20 states that night and I never turn my beams or turned the power above 3 watts. Memorable night!

Hi Adam. Still a great video. I've watched it again to get some ideas. I want to build a 5 ele yagi for sota 2m FM & ssb. I am now using my other account. My other account was/us Motters Motters. Will have ago at building one of these. I've been reading about them, about gamma and hairpin matches. I am not technically minded so I guess it will be trial and error with that part. I've seen people use a strip of wire across the two elements on a tape measure yagi. Should be on the build in the next month. Motters M7TRS 73 👍🏻

[@thekhakihat3233]

Hey Adam. Great video. Thanks for taking us along. Quick question: how did you match impedance for that antenna?

[@2metercrew389]

I sure wish I would’ve known you were going up there… I guess I missed out on this one

[@K6ARK]

Oh, this thing will get out to play again. Not to worry... Would love to try to get you from Cerro Noroeste or Mt Pinos north of LA.

[@phildurall7466]

Delightful video Sir!

[@fededevi1985]

They sell aluminum telescopic ladders that extend to 5.5 meters. Weight: 14kg but if you cut off only 1 mast will be probably less than 5Kg. On top of that, if you can stabilize it you can probably put anorther 2+ meter of support since the ladder is made to support 150Kg.. If you manage to keep it straight up. Probably doesn't matter that much for 2m but still..

[@glensaamanen720]

Another awesome video. Do you have a video on what your typical none radio day hike load out is ? Pack boots clothing and such ? I guess it would also depend on the season ...

Fantastic video vlog thanks for sharing I hope to hear you one day on HF... 73 Vic KE8JWE

[@nativetexan9776]

The bad part about using an amp on simplex is it gives the receiving station a false sense of a contact they will hear you but if they are running without amp, you will not hear them.

[@K6ARK]

Excellent point. That can happen, but the pre-amp on SSB and CW helps on my RX side, as does the 6 element yagi. I was constantly adjusting my power during the activation from 20w up to 160w. Worth noting, Joe, KE9AJ was running just 5w on his end when we made contact. Fun stuff!

[@gustav316]

After further research, it was actually a Norwegian woman ham, activating in Svalbard!

[@seandrake7534]

Did you build the yagi antenna or did you get it some places is yhere a video on it

[@ericcbn8210]

Very interesting video and Nice job for this antenna build. What transciver do you use in this video ? 73 from France.

[@K6ARK]

Eric, I use the Yaesu FT-857d for 2m SSB and CW. It works very well! Hopefully Yaesu will come out with a new version soon.

[@jmount1200]

Would a 5 element (2 elements spaced similar in spacing to the 3 element) then attached to the front of your 3 element provide a considerable amount of gain for a S2S contact from Southern AZ? I guess it is worth a try.

[@mikecampbell410]

Do you have a build video for the antenna ?

[@K6ARK]

Not yet, but like the 6m beam, I am working on a video that walks through the construction methods I used, and will share the MMANA files for the designs. There has been lots of interest in these designs, so I'm going to try to get this video (or series if it needs to be) out in the next month or so.

[@weberfire1979]

I am also interested in a build video for this

[@lawrence1md]

Do you have a video on the Yaqi build?

[@frankwc0o]

When you use your Yagi in a vertical polarization, do you us SSB on 2 meters?

[@harmerdean]

Are there plans for building the antenna? Try SSB on 144.200 sometime.

[@K6ARK]

I will attach a MMANA file as soon as I have a chance. I also plan to do a few videos on portable yagi construction tips - how I make the elements, the boom, and the match. I did work SSB from the summit, making one contact, and even called CQ on CW for a bit but had no takers there.

[@Kody10538]

What part is it that you used in the middle of the channel where the threaded bolt goes through? Seen at 6:13

[@rossrobinson7943]

So how much was SSB vs FM? There don't seem to be many HTs with SSB support.

[@PatAutrey]

So when making a 2 element YAGI is it better for the other element to be a reflector or a director

[@omarjensengarcia2153]

Is it okay to ask the diagram of your yagi? Thanks

[@CraigSotelo]

What frequencies do you use for calling cq on 2m ?

[@K6ARK]

A mix, depending on what's common in the area. In SoCal, 146.52 national simplex calling frequency on FM, or 146.580 which is the adopted "adventure" frequency and common SOTA op simplex FM frequency. For SSB and CW, 144.200.

[@adlucem9845]

Ham radio would be cool but there no way I'd ever ask the gov to speak. dont you feel embarrassed getting a ham license?

[@K6ARK]

Not in the least. The license helps ensure parts of the bands are dedicated for our use and keeps users from causing problems for others. FCC enforcement (or lack thereof) shows that one could execute similar levels of communication without them even noticing, you just wouldn't have many others to talk to. The call sign is needed for the radio games I like to play. The only thing I would be embarrassed about is being so paranoid of the world around me that getting an amateur radio license sounds like a threat.
