"Nothing scientific" Exactly. Receive is a pretty bad way to compare gain unless you did so with instrumentation. Signal to noise is how we usually judge signal strength by ear, and if the gain is less so will be the noise. I can hear a LOT of stations on antennas that are so bad on transmit that nobody would be able to hear me. Your "slightly less" could easily be several dB, and "not bad for an old design" is hardly a recommendation when better designs are available. Dave AB7E

Mosley bashing is never ending.
So I had to see for myself.
I was given a Mosley TA33 tribander. It is certainly well built.
I mounted it at 50 ft pointed towards Europe.
I also have a TH7DX at 50 ft that I can point in the same direction.
I did a few receive signal comparisons. Nothing scientific but it gave me a 
rough idea how the TA33 performs. Generally equal to or slightly less than the 
TH7DX.
My conclusion is the TA33 is not that bad as some claim and not bad for an old 
design.

strength then other tribanders?
They are not, as proven by proper range testing.

My first tribander (50 years ago next year) was a Mosley TA36 ... I
quickly replaced it with a set of Hy-Gain antennas (204BA, 155BA,
105BA) and never looked back.  Comparatively, the Mosley was a lead
(HEAVY) dummy load and a set of dipoles performed as well.

Suggest you get catalog from Mosley and consider one of their monobanders
if you don’t want traps.

Monobanders are a great idea IF you have the real estate to rig them.
Moseley's big tribander came in dead last in the testing that N0AX and
K7LXC did in 1999. It even had negative gain (dBd -- with respect to a
dipole) on 15 and 10M, only 0.7 dB on 20M.
