Don't worry, I'm still working on the series of articles I promised, oh, a year ago?
I've rewritten it several times, and it's 90% to the point of adding the illustrations to it.
I'll probably take photos of the various types as I build them out in the back yard, as I don't draw things "on the computer" very well, and I don't want to swipe random pix off the Web.
When this is finished, I'll post the sections of it, and if I can find a free place to upload a pdf for free access, I'll do that, too.
So hang in there, it's "In Work" as we used to say at Boeing!

Every so often when I'm checking my PiAware ADSB receiver/display I'll notice an aircraft with a flight path that catches my eye. I...
LOL, I know ALL about field expedient HF antennas... :-)
ReplyDeleteYeah, I do, too!

These will be easy-to-build and deploy ones that you can make out of "whatever" you have laying around.
I've made both dipole and vertical antennas from scraps of extension cords that I dug out of the trash. Just about any copper wire will do.
Someday I'll write up something about the time a buddy of mine and I literally loaded up a wet string on 14MHz.
It was wetted with salt water, but still, it was a "wet string"!
Are you willing to put up with an autotuner? LDG and MFJ produce cheap, effective tuners that make this much less difficult. I have an off-center fed dipole, cut for 40m, that tunes from 40 to 6m with the common (3:1 limit) tuners built in to radios (and my Icoms have always worked well beyond the stated 3:1 limits). I took an 18 MHz dipole on a trip a while back. Tuned all HF bands, with and LDG autotuner, with varying degrees of effectiveness.
ReplyDeleteI *have* an autocoupler at the base of my vertical.
