Listen to what Steve and Joe are saying, they are consistently right about
antennas. ...or read the book "HF Tribander Performance" by K7LXC and N0AX.
There are any number of antennas that are available that have PROVE track
records.

Subject: Re: [TowerTalk] Mosley Antenna Question
I too have had Mosley antennas over the years (TA33 and TA36) and in both
cases I noticed a significant improvement in performance when I replaced the
TA33 with a Cushcraft A4 and the TA36 with a HyGain TH7DXX (neither of which
is a "high performance" tribander by modern standards).
K7LXC will not "talk his book" but I will say that multiple unbiased antenna
range tests - including those reported in the K7LXC/N0AX "Tribander Test
Reports" - have shown that the Mosley antennas perform more poorly than any
other manufacturer's multiband yagis of similar boom lengths. Some tests
even showed certain Mosley antennas had
*loss* compared to a dipole at the same height above ground.
