I found this one being quite good https://vk6ysf.com/unun_9-1_v3.htm my only additional recommendation is to also wind this https://vk6ysf.com/balun_choke_balun_hf_reisert.htm and insert it in the same box, connecting the choke at the output of the 9:1, this will effectively stop the feedline from b...

I am considering using an AX1 antenna with my QRP radio for POTA and other times when I can not use a wire. I realize that it is not as good as an EFHW, but has anyone had good success with it? I read the article in QRPer about it, but would like to hear other user responses. I plan to use SSB as I...

FT-817nd, with the usual complement of field gear: LDG Z-817 tuner (kinda goes with it), whatever wire antenna I'm trying out at the time, Portable Zero rails, SOTAbeams speech compressor, 4.5 AH Bioenno batt, signalink and a recycled linux laptop, and (the BIG ONE) a rite-in-rain notepad. Yeah, bo...

ok, this one is probably crazy, but... imagine reaching a POTA site, laying down some radials , connecting the trx to the coax and finally tying the antenna wire (whatever lenght will fit) to the bottom of a drone, the drone, controlled by someone else takes off vertically and pulls up the antenna, ...

Can anybody offer thoughts on the use of dedicated counterpoise wires with 9:1 Random Wire antennas for QRP operations? I have a Packtenna 9:1 with 71 ft radiator that I have used with some success with only the 15 ft coax feedline for a counterpoise. I also have a Tufteln 9:1 with 35 ft radiator a...

Great summary, Andrew. Thanks. For those interested in an off-the-shelf tuner (rather than building one from an online design), I tune up my Tufteln random wire antenna (the same antenna featured by Thomas in his activation of Cap Tourmente National Wildlife Area (VE-0012)) using a little MFJ-9201 ...

Great synopsis on the random wire antenna, Andrew! One thing I would add, for people finding this having no previous experience with random wires, is that this antenna requires a "tuner", or matching device. Many radios have one built-in these days, but many others don't. Random wires are...

Let me start by saying that, what follows, is just a bunch of personal notes about the so-called "random" wire antenna, the idea of posting this came after reading some comments on QRPer.com For the folks interested in building their own "random" wire antenna and not willing to d...
