Delay Lens Antenna Update
- Hello All:
A few months back I posted an account on how we recovered a delay
lens antenna from an AT&T site in Washington state, I thought I'd
give you an update on what we've done with the antenna since then.
Unlike the KS-15676 horn antenna, which is delivered to a repeater
site as a one piece, completely welded assembly, the delay lens
antennas were originally shipped to repeater sites disassembled and
packed into cartons. Generally the same contractors that performed
construction of the tower would assemble and install the antennas.
When we were at Clyde, WA back in February, we reversed the assembly
procedure, basically removing all of the 300+ bolts that hold the
antenna together. When that was done, we ended up with a stack of
flat aluminum panels that we easily loaded into the truck we had.
We brought the pieces back to one of the AT&T sites we now own, since
then we have been cleaning up the antenna parts in preparation to re-
assembly. All of the assembly joints of the antenna were loaded with
an electrically conductive, nasty smelling caulk, in addition,
silicone caulk had been applied over the other caulk to help make the
antenna weatherproof. We have been stripping off all of the old
caulking on each piece of the antenna, we now have enough cleaned
pieces to start re-assembling the antenna. I just posted 4 photos in
the folder in the Photos section labeled "delay lens antenna", two
photos show the ID tags on the antenna and mounting base, two more
photos show the start of assembly of the lens housing section of the
antenna. As we progress with this project, I'll post additional
photos, I'm guessing it will be a number of weeks before the re-
assembly is complete. In addition to cleaning parts, I still have to
fabricate several brackets and other parts that were missing from the
antenna when we picked it up.
