It is 900 MHz and users are few and far between. If usage picks up, I will

I did however use a Arcomm audio delay board and accomplished the same results.

It wouldn't be impossible that an applications engineer at the factory might be
able to assist. Decibel went to Andrew and now is CommScope.

Comprod makes dipole arrays with a screen reflector, at least for VHF, not
sure about UHF. I'm looking in the catalog and it shows a backside null
close to 20 dB down from the main lobe.
The screen reflector should be nominally about 1/4 wave behind the radiator
for maximum forward gain. It
I was thinking about the possibility of him converting the DB-411 into a
corner reflector. Might work. Get the info from the Decibel corner reflector
and apply it to the DB-411.

I have DB 664 (VHF) clamped directly to a tower leg with all elements
facing one direction and it works nearly as well off the back side range
wise.
I think you will have to go with a real corner reflector to knock it
down any noticeable amount. Experiment away and let us know your findings.
Hi guys,
I have been reading this list for a long time and now its time to take the
plunge.
I need to build a portable UHF repeater for my SAR team. So, I am looking for

Kinda like I want omni coverage except for this 45 degree area. I don't think

I'll check Comprod's web site.
Thanks and 73,

Tom and Skip identified the problem as input levels being too high. I
got this straightened out, and the problem is solved. Thanks for the
suggestions. I appreciate the help.

Dan,
Before you make any decisions about selecting any specific antenna for your
application, you need to know or specify top or side mounting. Then you'll
need to consider any and all metallic objects present in the near environment
of the antenna because they constitute reflective or
I'm recrystalling this unit and am working on the TX. The first part of the
tuning procedure states to monitor a circuit point with a VTVM but there is no
test point to connect to. Worse, the only way to physically get a connection
to this point is to completely disassemble the TX, which
The TS-64 does indeed encode a reverse burst STE signal. Unfortunately, it
has the 180-degree phase shift, because that is really easy to do. It
cannot encode a 120-degree phase shift, so that means it is fairly useless
with Motorola and a few other radio brands. When I contacted Comm Spec
