Re: Bring lots of different types of antennas, just in case
Ok, now I feel like a dummy. I have a TransWorld TW2010 (pretty much a commercial version of your double T bar) but I was concerned about taking up too much space in the car. Next time... if the antenna is this one https://www.dxengineering.com/parts/dxe-tw-2010-p then once closed it isn't too big ...

Re: EFHW/RW - Attaching wire to balun
Considering how easy it is to build https://vk6ysf.com/unun_9-1_v3.htm I think it won't be a problem building one of them as desired :) the "ground" goes to the counterpoise(s) or to ground stake, a small IP66 electrical junction box will host the toroid, the wire connectors and the coax o...

Re: Bring lots of different types of antennas, just in case
the double t-bar may be unsuitable for some spots, but imVVHo will serve you well in all other cases when you can't set up an endfed wire

Re: Bring lots of different types of antennas, just in case
for "no tree" or "no wires up trees" situations, consider the *double t bar" antenna
https://www.qsl.net/hb9mtn/hb9mtn_vertdip.html
a ground stake or a tripod will support it, and while the gain isn't high, the takeoff is low, even if the antenna is near ground

Re: EFHW/RW - Attaching wire to balun
for fixed ops one side of the antenna may be suspended to a rope tied to a weight, so that the antenna wire is free to slide, for portable one may use an alligator clip, if someone/thing trips over the antenna wire the alligator releases it

Re: Cheap 32’ carbon fiber mast
Also, carbon fiber masts are conductive, so they're a "no go" if one wants to use them for a vertical antenna, better looking for fiberglass poles, those will do double duty to both act as center support for a dipole/doublet or to put up a vertical antenna just by hanging the wire at the t...

Re: RG316 recommendation
Late on this one, I suggest looking at "Messi & Paoloni" products, and not just coax cables, but connectors too; I've used their products several times and never had to complain

sBitx - any good ?
Just noticed that the same folk(s) behind the uBitx made a new model, this one is called sBitx https://www.hfsignals.com/index.php/sbitx-v3/ and seems to offer quite a buch of features, but then it's an SDR and I wonder if it may be plagued by the same issues of other SDR based rigs, including the f...
