Subject: Re: [TowerTalk] Antenna Standoff arm
This could be tricky. I think you need to run the coax to the antennas at the
top of the tower inside the mid-level rotator ring, assuming there is room
enough for them to freely slide without getting caught. I mean inside the
ring, not inside the tower. I'd want to look at a ring rotator first before
buying it to see if this will work. Not sure what else to suggest, but If I
think about it long enough I'm sure I could come up with a solution. Either
that or my head will explode.
## here's the 'fix' when using crank up tower's and a ring rotor [ or a
fixed yagi on the side of the crank up].
Install a 2-4" pvc pipe, with flares at both ends....and install it INSIDE the
ring rotor. It has to be fairly long as well. the coax/control cables for
the yagi's /rotor at top of tower will all have to pass through the INSIDE
of this 2-4" OD pvc tube. The tube is oriemted, such that it protrudes
ABOVE the ring rotor itself. Tic gen makes special adaptors so a 1032 tic
ring will work on my UST-HDX-689..[89' towr]....and will fit
at both the 72' level..and also the 55' level. The 3 big pis are welded to
the tic corner brackets... and simply drop into the tops of the tower section.
It's a solid assy. Since the yagi on the rinf rotor rotates 360 deg,
all coax for the upper ants HAS to 1st pass through the 4" pvc pipe.
## Now if the lower yagi is FIXED.... then u don't need the pvc pipe... and
all coax /rotor cables for the top of tower can simply come down the side of
the tower...and reg coax stand offs can be used.
