I used cable lengths below rg223

Have a Phelps Dodge 526 UHF duplexer that's missing the cables from the
tee to the cans. Google came up with one vague reference where someone
thought these cables were 12 inches long. Is there a chart or formula
somewhere to determine their proper length?

Good timing, I just now have one on the bench tune up. This 526 was
originally on 454/459MHz. Both cables from the tee to the cans are 12
inches. This is measured from the far end of the N connector on both
ends. In other words, it includes the length of the N connector. The 2
cables are
good morning Martin,
Why not use a db-201 folded loop ground plane instead? It is half the length
of the db-212 which needs at least 2 bays to be halfway decent. (they make em
with 3 and 4 bays also. the pattern off of the 4 bay is the best for coverage.
The 3 bay has too much 3 leaf

a j-pole for repeater use is ok too, just real long!!!
I tried a J-pole for my 53.370 machine some 14 or 15 years ago
and found it useless for full-duplex. It's a great simplex antenna
but it really fell apart for repeater use. I tried everything to
decouple it from the feedline and
Arrow Antennas has a fairly robust 6m ground plane:

Hi Folks,
I'm looking for a Low Band Micor Repeater exciter
and Final that I can put on 6 meters. (I
already have all the other stuff)
I have a High Band version of same stuff to
trade.
Figured I'd ask here first.
Thanks,
Tim W5FN
