. Super Sataionmaster Disassembly

Anyone have info on the proper way to disassemble a VHF Super Stationmaster
antenna (PD220?) This one has 3 flat-head allen screws in the aluminum base
section about an inch from where it meets the fiberglass as well as two
bolts
in a ring accessible from the bottom where the connector is. I've removed
all
of them but wasn't able to get anything to budge. It could be that it just
needed a bit more persuasion but I thought I'd ask before I break anything.
Also are the 3 radials around the base standard on all models? I'm missing
them
but figure I could easily fabricate something if they're needed. I think I
read somewhere they were not necessarily a ground plane" but a decoupling
device. Anyone have dimensions/construction info for it?
Thanks,
Steve
Steve,
There is usually a set screw of some kind in the top cap that must be
loosened to release the innards of the stationmaster.
The three radials are usually clamped on near the top of the base tube
and are flat pieces of aluminum bent out at 45 degrees or so. They are about
6 inches long for UHF and 18 or 19 inches for VHF past the clamp. They are
1/2 to 3/4 inches wide. A stainless hose clamp will work for the clamp. I
don't know how important these radials are as I have seen as many without
them as with them. Can't hurt to have them. YMMV.
