In addition to my last posting, I forgot to mention one point concerning
the base sandwich. Besides the metal plates having the three holes for
the clamping 1/4 inch bolts and the UHF female connector, it has an
additional open hole straight through the sandwich. This is the weep
hole to leak

Hello All:
We finally took the 220 antenna apart, and it was an education. I would
like to share our experiences with you.
First, depending on the vintage of the antenna production, these
antennas may be assembled and disassembled

I have removed these three allen head screws, however the epoxy is

The PD-200, also known as the Stationmaster II is a very narrow-band
antenna designed especially for simplex use or for repeater systems
having separate RX and TX antennas. It is not a good choice for duplex
service, even on 2m. The PD-200 has only a 1.5 MHz bandwidth, and it
must be

Joe,
The latest RFS/Celwave catalog identifies the 200-series antenna as
the Stationmaster II.
I wonder what is different about it. I also wonder how you tell the
difference since both are PD200s (or is there a new suffix added?)
While a PD-200 ordered with a center
The specs are identical. I wonder why they changed the name.

I looked at a VHF PD-200 in my garage that I had apart a few years ago, the tip has a small allen screw in it. I think I loosened this screw to get the guts out of the radome. My PD-200 is noisy, this is usually caused by joints that have become intermittant. I was never able to find the bad

must be removed and the tip heated with heat gun. Cap will come off. Don't
overheat fiberglass. The complete antenna then can be removed

We were given a 5.8 db Gain Stationmaster for the 220 band, and it seems
to be very sick.
There is no DC continuity directly across the UHF connector, and the
VSWR is horrible!
We are in the process of taking this antenna apart, however
