Welcome! Remember, without guys like you, the big guns
have no fun!
I'd suggest replacing the Mosely (pre-computer design
and traps, if I remember correctly) with either
a Force 12 C-3 type (C-3E or C-3SS, depending on space
constraints) or a SteppIR 2 element. Both are fine
antennae, computer designed, with excellent mechanical
and RF performance. Neither are cheap :-)
I used a C-3E for years as my primary antenna, and was very
happy with it. I replaced it with a C-3SS as my second
radio antenna, and was very happy with that. Now I run
a 2 element SteppIR as my second radio tri-bander, and I
am very happy with that :-) You really can't go wrong with
either antenna - and they will both do well on your current
tower.
I would think that anything larger, certainly a Skyhawk,
Force 12 C-19XR, SteppIR 3 element type antenna might
be a problem on your current tower. Actually, to be clear,
I think it would be a problem for your rotor. 35' of
Rohn 25, if properly installed, can easily handle one of
these larger antennae. If the tower is guyed, has a good
base, and you are willing to step up to a bigger rotor,
any one of those larger beams would be a nice improvement.
Best 73 es GL!
