The FCC rules on narrow-banding seem to be contradictory when it comes to

On one hand, the FCC states that All below 512 MHz which implies VHF low

Thank you VERY much for trying this and letting me know. That will save me a

I have read an article that uses 1/4 superflex with PL259 and UG176 reducers,

is cheaper than RG214

I just took a piece of ½ Superflex that previously had a connector on it
and tried to place a PL259 UHF MALE on it. The corrugation on the superflex
is larger than the ID of the connector. The connector will go over the

I've used 1/4 superflex with PL259 reducer. Works fine. Seems like I had

3/8 superflex works pretty good with regular pl-259.
It screws right onto the jacket. Then solder the corrugated copper
through the holes of the pl-259
I've used the 1/4 w/reducer as well. I also drilled the reducer to get all
the way to the copper.

Thanks Chris.
So using 3/8 superflex and silver PL259 seems tight enough? Would be
better than using silver connector and nickel reducer. Just trying to
build two 3' jumpers to replace old RG9.
How tight can you bend the 3/8? I might also need to rebuild a duplexer

I pulled off linking two adjacent 224MHz Repeaters.
The repeaters are on different 30 mile distant mountain

One repeater has an on-band linking radio (Alinco DR-235)
set up on the adjacent frequency. As an example... 224.960

I use the TRAM 1480 (also Workman version) in several installations and they
all work well. I have not had any problems or failures. The 1481 has
additional collinear sections on top (making it about 6 ft taller). The
TRAM and WORKMAN antennas are ELECTRICALLY similar to DIAMOND
I really like the 3/8 superflex.
I can usually find a 30' piece on ebay with factory n male connectors on it
for cheap.
Then I cut a length leaving an N on and put a pl-259 on the other to go from
bigger hardline to a diplexer or other UHF fitting bit.
Keep cutting from that end for other cables
Chuck, if you use a reducer made for RG59 (and RG8X?) there's no need to drill.
Perfect fit.

I wasn't sure, but that rings a bell. I think I had to drill out the ones
for RG58 because that's all I had on hand. You know how that goes ;-)

Hi Rodney and others.
The CAT5 cables are definitely shielded and I suspect that they are properly
terminated.
There are 10 CAT5 cables in total and an LMR200 cable. I suspect the LMR200
goes to a GPS unit which is on the tower. Six of the CAT5's go to the six
panels and likely the other four

Thanks for the information. This gives us an idea of what to expect when we

I would also look at the termination of the Cat 5 cables as well as
looking at any router which is in the system-we have seen, as numerous
sites, that Wi-Fi switches and routers are not very well shielded and
produce a TON of garbage in the 140-172 MHz band at least-I am not sure
what components
Serious question: Why is linking two repeaters via RF okay and
linking via IRLP wasting everyone's time?
Isn't the owner also wasting the time of the people in the

Is the interference present on your receiver when your transmitter isn't

You can always use *less* than the *maximum authorized* bandwidth. If
you couldn't, all the radios with low deviation would be illegal.
For that matter, try finding a Low Band radio on Land Mobile that uses
20 kHz bandwidth. All the ones I've seen use 16 kHz

The manual I referred to is the Motorola manual. The FCC ids are
usually given up front near where the model table data is. Some of the

First step is Google the ID and see what you see. Looks like 42-50 split.
