Antennas for covert install.
« on: April 12, 2019, 1917 UTC »
So, I'm wanting to build a few solar powered beacons to stick on mountain tops. They've gotta be kinda covert so people dont mess with them if found so I'm wondering what kind of antenna I could use that would be cheap and easy. It seems like either a halfwave dipole or an end fed is the most common, but it makes for a pretty long wire/rope.

Any ideas? what have others done?

BTW i've had a little solar beacon on the air for a few months now, but I haven't seen any reports. Its on ~135572 but isn't extremely stable. PIE @ 10wpm. Located in Grand Forks BC, Canada, right on the Washington border.

You want to set up multiple beacons?  Awesome.

In addition to a 22m beacon, you should set up beacons for higher and lower frequencies.  The 2, 4, 6 and 8 MHz bands are popular.  I also recommend setting up a beacon on 11 meters as that can have some spectacular results (well, it will when the solar cycle picks back up again). 

In regards to stealth or covert antennas, wire antennas are the way to go.  Since you're dealing with low power transmitters you don't need a thick wire.  The humble 1/2 wave dipole is a sure bet, but there are other options too depending on what limitations you have.
