That's great advice, Larry!

The most likely answer is "it depends." Despite the theoretical differences
between the antennas, there are situational differences where one will
out-perform the other: quality of ground, height, propagation, direction to
receiving station...
BUT, you can measure those differences yourself. Tune-up on the Buddistick
in the CW portion and send the string "test test de <your callsign> <your
callsign>". Move your VFO 5 KHz and send the same string on the random wire.
Then open your browser to the Reverse Beacon Network's search page and enter
your callsign.

Compare your received signal strength on each antenna by the stations who
heard you. Run the test a few times to minimize QSB and propagation fading.
What do you get? The results ("which is better?") may be different as you
move from one location to another. If you can carry both antennas use the
one that's working.

Hey folks,
KX3 and Buddistick owner here. I've been getting a lot of feedback that I
would get better performance (more contacts) with a random wire vs my
Buddistick. So, while I've noticed that reception is much better with the
wire, with the Buddistick, I get 1.1:1 according to the KX3 and have made
all my contacts with the Buddistick.
Now, recognizing the DIY nature of our hobby might lead people to recommend
a random wire over a commercial antenna, if I actually manage to deploy the
wire "optimally", should I really see performance equal or outpace the
Buddistick? Or am I simply finding bad luck the times I try to get a QSO
over a wire?
I've tried deploying from a 30' pole sloping down, the hypotenuse of the
triangle pointing to my desired direction. I tried deploying 40+ feet
between two trees about 12' off the ground. Now I'm going to get a Zebco 202
and rig up my slingshot to deploy vertical. But honestly, I can get the
Buddistick up and running in about 3 minutes....
Mainly, I'm on 20m and maybe I haven't read the right book on random wire
antennas, but I would appreciate the group's thoughts.
