Mike,
Are there any other markings on the cable? Specifically, I'd be looking for
the following:
FSJ1-50A
This is 1/4 Superflex - about the same size as RG-8X...
Velocity factor for this (FSJ1-50A) cable is 84%

I have had good luck with 222 MHz Ringo Ranger. It is a little heavier
construction and has a reasonably flat pattern.

Hi guys .Can anyone advise the difference between the 25 watt and the 40
watt version of the above radio and can the 25 watt version be upgraded to
the 40 watt

The sm 4450 is a 16 channel 40 watt uhf transciever. There is a 25 watt uhf
model but it has only 4 channels and is capable of 40 watts also by adjusting a
pot inside but it does not have enough heat sink to run at 40 watts more than a
few seconds so I would not advise it even with a fan.
thanks.The sm4450 radios I have here are identical outside to the ones that
produce 40 watt but only reach 25 when the avc is turned up
They are all 16 channel with a heatsink .one of the models are sm4450sc

Yes, it does have that marking. Appricate the link. Not to be redundant, is
the length I need to use is 1/4 wave for connection to cavitys, right?

No problem on the link, Mike. Glad it as the same stuff!
A 1/4-wave cable on an open circuit introduces a short... If I remember
correctly (and I'm sure if I'm wrong others will correct me!) you need a
1/2-wave cable between cans.

The side arm is made of welded aluminum and the top arm or stabilizer
is PVC. Last check of the antenna the radials were tight and nothing
in the near field that I can find is loose.
Hopefully this weekend we will be able to have a close look at
everything and do some testing to determine

I don't recommend the Ringo Ranger for any duplex application. The gain is
overstated they have feedline decoupling issues. Even if you use

Merrill,
The Motorola TLD2602A is a 100 watt, continuous-duty power amplifier used in
the MSR2000 station. The exciter for that PA is described as providing at
least 0.75 watts drive. There is no range specified, but one might
reasonably assume that the drive would be around 1 to 2 watts.

Bob, What do you know about the HUSTLER Spirit Series of antennas.any good?

Mike,
I normally use standard silver/teflon PL-259 connectors with a silver
plated ug/176 series adapter for the 1/4 superflex. To turn a
standard connector into a Andrew clone, just drill about a 1/8 hole
through the adapter, about a 1/3rd of the way down from the top.
