I snagged the 2.0 version. Great design. Great to see ppl able to make and sell things from a home market. America 🙏✌️🇺🇸

[Sonicgott]

I’m a huge fan of the G 90, because of the tuners massive tolerance. I use it with a custom built antenna out of speaker wire. It actually works quite well.

[mikesradiorepair]

I use 9:1 UNUN non resonant end feds in the field and have never needed a external tuner. Tuner in the radio does every band from 6 to 160. I usually use a 72 foot wire with the coax as counterpoise and a choke at 42 feet. Best antenna there is, not by a LONG shot but it gets me on every HF band plus 6M in the field.

Correct code for a 10% discount at Messi and Paoloni is HRCC-73, not HRCC73. The latter was not accepted for the discount. Thanks for the excellent video. Mitch NK3H

[mcmichaeltube]

Thanks, Josh. I use the random wire when I want multiple bands in a smaller footprint than I can get with a EFHW. But normally I tend toward resonant antennas.

[TheGeekiestGuy]

Right on. I'm working on a 40-meter antenna as I write this comment. I got a xiegu x6200 for my bday, and the xiegu amp is still somewhere in Florida atm. So I'm gonna make a resonant antenna and use my homemade balun. I hope to get on the air with this tonight. Thanks for always somehow doing content that sounds with what I'm doing. It's like the ham hive mind is running strong these days. I hope everyone is having a good one. 🤙🏾

Hey Josh. Excellent video. I have been making various end-feds with the fishing line you mentioned and can confirm that it is pure copper. Made in America copper as well. I have been using it with chalk lines reels, but love your clothes line idea. So much so I ordered a couple. Keep up the great work.

[HamRadioPortableOperations]

I did the same with the retractable washing line reel but the one with a pullout handle makes it easier for winding up and I used Sotabeams lightweight wire. Works a treat. 👍

[robertmeyer]

Nice video. That a neat UNUN ! Love that Pota Flex coax ! I got the 50 FT POTA 7 reel kit and case. Did KW POTA just fine ! 73

[the_mad_swimbaiter]

I carry a 9:1 packtenna for my x6100 and the 49:1 for other qrp radios. On the new Mountain Topper, Tim N9SAB agreed to make me a linked 20/15 m linked dipole so I can rock the SOTA

[dorvinion]

Having a 705, I also prefer to use resonant antennas - typically a 49:1 with wire for 10-40
With the ATU-10 I can usually get tunes on 12, 17, 80 (maybe 30 too)

Kinda feel like if I'm gonna use over 60ft of wire I may as well just use a 49:1 so I get resonant where possible, and use the tuner where its not
And if I can't use such a long wire use a 9:1 instead

[ajisotadxing]

I use 9:1 in the winter sota season when I want to do a quick activation and cover many bands fast.

[akademic]

The feed point of an antenna has an impedance (Z) (ohms). The ohm impedance Z varies between the halfwave(high- 2, 500 ohms) and a quarter wave (low- 500 ohms) and everything in between. If using an EFHW expect a high Z and use a 49:1 reduction transformer (usually an UNUN) to match your 50-ohm feed line. If using a random length, try for one (see table) that is not a half wave at any frequency in use. Connect a 9:1 unun to your feedline and hook up the wire to the other end of the unun.
Since impedance is complex, there is often additional ohms added or lost by ground or capacitive effects. To be perfect, you would in practice need an antenna tuner that replaces the UNUN and loses the other ohmic effects too.
Remember, the longer and higher the wire, the more efficient it becomes in TX and RX. Try for a half wave in height. Trees are your best friend here.
Good luck. KF3

[Ammed_KNSTX]

Good video Josh!! I bought and built the antenna but have not played with it yet.

[bhamptonkc]

I have been asking the random wire length question for years. I run an icom AH4 tuner and it says to avoid 1/2 wave lengths I use ace hardware clothes line which works surprisingly well, I have lengths from 35 to 135ft I am portable and I do NVIS and reg t from on the ground to 6ft typically

[brianfields]

Resonant over random every day for me.

[abeabe]

I love my K6ARK efhw kit on 40/20/15/10m with my x6100. I have another kit I've been thinking of doing a 9:1 on it

[edcnorcal]

Sweet camping table! Where did you find it?

[theradiorover]

The only time I got an RF burn was from my EFHW/49:1/KX2 combo. I was using ear bud headphones and got a hot ear. The headphone lead is now wrapped around and inside a clip on ferrite. Problem solved.

[ghostmandka]

Another great video! I've seen the feed point in the high position and at the ground. Which is the correct placement?
