Antennas for postage stamp size lots
« on: July 22, 2021, 0151 UTC »
Tiny yards are a challenge to put up a reasonable HF antenna, but there are a few things you can do.  See https://forums.radioreference.com/threads/antennas-for-postage-stamp-sized-lots.429144/

Quickly skimmed the link. An active e-field antennas can work okay if you are not dealing with lots of local EFI/RFI and can accomplish RF grounding besides simply relying upon common-mode currents on the feedline as a counterpoise.

I have deployed two PA0NHC-style miniwhips at my QTH located on a quarter-acre lot in a neighborhood, though thankfully my noise levels are usually decent. Mine are RF grounded to their 10.5' masts, which each are sunk about 3' in the ground, plus chokes on the feedlines as they depart from the base of the masts.

A crossed parallel loop is another option for a small antenna. While certainly not as "good" as my full sized wire antennas, it does a very respectable job for the size: http://www.radiohobbyist.org/blog/?p=2340
