Mythology went out with the Greeks and the Romans. Modern antenna

However, there are alternative religions.

Well, I've come to a few conclusions.
1. Dipoles with a 1:1 balun work very well.
2. See #1. However, the trees and other things they are attached to
are hard to rotate.
3. Vertical antennas load nicely. So do Bird Termalines. And they
radiate about the same.
4. See #3. If I had room for a bunch of radials to make the vertical
work properly, I'd have room for a real antenna.
5. Yagis do nicely. _IF_ you have the tower and rotor to put them on.
6. A 102' doublet with open wire feed line and a tuner works amazing
well and considering the cost difference is flat out outstanding.

#4. Having moved to a small rural town in central Texas, I have
a lot of room now living on 1/2 an acre.

I already had a used 40' tower and was given the tuner as a bribe to
try the 102' doublet. And I had a 500' spool of #14 THHN house wire
to play with.

Isn't half the fun of all this seeing what works well for you?

I have an MFJ-928 ATU at the feed point of an elevated 43' vertical, with
a half dozen radials of various random lengths. It works great for
30/20/17/15. It starts making significant multiple lobes above 21 MHz.
I'm going to try a coil for 80.
