Switched manually? You mean you have to climb the tower to switch them?
Or do you mean switch them REMOTELY? You can do that over the coax,
like my design which is similar to the Ameritron RCS-4.
Weatherproof enclosures are available quite inexpensively over the
internet. I've purchased over a dozen that way.
Good luck,

The problem is that they are switched manually. I've got a pair of DPDT
relays NC thru and pulled preamp engaged, for VHF and another pair for
UHF. Wish I could do it your way. Need some sort of weatherproof enclousre
as I'm in el89 central Florida.

How about putting the preamp up on the mast, just above the lower antenna?
That way, the ONLY coax going down past the tower-top is a single run to
the preamp. You could affix the coax from the two antennas ABOVE the
preamp, moving the loops of cable away from the tower-top.

Up that is!
Hi All!
I've got a 20' stick of Rohn 25 with a Yaesu 5600b (split with the az in
the tower on a Rohn plate and the el up on a mast) rotating a pair of M2
antennas. Installed with the antennas are a pair of frames to route the
cables from the antennas to the cross mast.
This feeds a box where the preamps are housed, about 3' down the tower. My
problem is that the loops from the crossarm to the have in the past gotten
hung up.
The tower is on a Rohn tilt base. When it goes up the next time, I'd like
it to be for a while. Do love playing with satellites, but the up and down
with the tower is a pain.
Suggestions, comments and photos appreciated!
