Jumper Size

[Ron]

Hello, I'm running a rci-2980 & 1k Scout AMP, should i run a 3ft. jumper
or a 6ft. jumper between the radio and AMP? Looking for the best
performance..
Thanks in advance.

Gene,
The best length to make jumpers is what ever length
will reach from one place to the next, with enough extra
length to make moving the radio/amp/meter enough to
disconnect it. If 3 feet seems long enough, it probably
is.

Use the length that makes it work the best.

In article <6390-38F...@storefull-148.iap.bryant.webtv.net>,

it makes absolutely no difference, what length jumpers you use, this is
nothing more than a perpetuation of cb radio misstatements and
falsehoods. if you don't believe me , ask dr handy andy,....cd is
out..........

Depending on the radio final tuning and the amplifier input tuning,
you may have to play with jumper length to get a good sound. Some
boxes like 10 feet, others like 5 feet of jumper. Experiment until
it sounds right. Also, too much drive sounds like sh!t.

Although coax is a capacitor, it does not make that much of a difference on
what length. Use the length it takes to get there, nothing more.

Don't forget coax is also an inductor and resistor.

As the input impedance of a lot of amps are not 50-ohms and the output of most
trannsceivers is 50 sometimes playing with the jumper length can make a
difference. If there is a mismatch though the jumper should be something
besides 50 ohm cable. You cant match 50 ohms to some other value with a 50 ohm
linear transformer(read as jumper). The best thing is to not worry about the
length and install a small coax to coax antenna tuner between amp and radio and
tune for best output. These cost between $10 and $20 at your local flea market
CB booth.

I agree with ham4fun, I have noticed a difference, sometimes minimal, with
diff length jumpers. I prefer to use atleast 4 feet and not more than 6.

Remember, the radio and amp MUST BE separated at least 3 feet, if not more,
to protect the radio from RF from the amp.

I have a uniden pro 810e which I feed into a Palomar 90A amp. pushing 100
watts. My Silver Eagle mic is just barely cracked open enough to move the
needle.My mic gain is set to 2/3, and I use a Yaesu FC-902 tuner
and this setup works fine.

CIAO!

Bull. If everything is set up right, the amp can be connected directly to
the rig. There should not be any RF on the outside of the amp or on the
coax.

Of course, I am talking about proper amps here - not a plastic cased
splatterbox.
