I agree on the Polyphaser suggestion.
Dont forget the AC power protection. I suggest Transtector SL plug in series,
not cheap, but they work quite well.
Also, how does a Polyphaser fail? Open? Closed? And are they truly multiple
strike capable?

Albert,
In the 30-50 MHz band, the antennas for a portable radio must be cut for
proper operation, over a very narrow range of frequencies. The length of a
whip antenna must be changed by 1/4-3/8 inch for every 1 MHz. Motorola
still offers the NAB6064B "tunable" antenna for the MT1000 radio, whi
I am assuming this is to be attached to the radio as a typical HT versus a
mag mount design?
Yes you will need to compensate for a little bit of GP loss, but this wont
make a noticable difference in length.
the last HT antenna I made was for dual band 2/70cm I used an old
tachometer cable as I

Okay, so you definitely have a mobile notch duplexer, which has practically
no bandpass effect since it works entirely by notching out the opposite
frequency in the split. Since the problem began when you changed the
antenna, my suspicion is that the new antenna's pattern allows more TX
signal to

If this is a 2m repeater, and the duplexer is mounted inside the VXR-7000
cabinet, it must be a mobile notch duplexer. I don't believe that such a
duplexer can perform with a 600 kHz split. Please elaborate on the make and
model of duplexer you have, and the RX and TX frequencies.

Sounds like a temperature related issue. You might recheck the duplexers and even knock on their housing while testing.

Hello,
Looking at W6NBC's article, he warns that operating in the harmonic mode
will result in higher losses. Maybe 2-3 db may not be unreasonable for
this mode. The other thing he warns about is maximum diameter of the
cavity. He says that the cavity diameter can't be more than 1/3

Hey,
You can use the external card, just shield it as well as possible by placeing
