Default aerial cable

Just installing a cb. The aerial cable is made up but a tad too long.
Somewhere in the back of my head is a voice saying,

"Don't just loop the excess, trim it!!"

Is that right? I've always been terrible at working with co-ax so any tips
to trim, is it a solder job?


Cheers,

Dave

Yes it is a solder job but its very easy. Just google for soldering a
PL259.

or better still if there are two plugs on the coax, cut of the excess
ammount and carfully unsolder the remaining plug to be fitted onto the new
cut.
check how it's been soldered previously and copy it,
always making sure the inner and outer never touch..!!


if it's 1 inch, 1 foot, or 1 mile, it's still 50ohms..!!!

No its a fallacy. Yes if your cable was dangling outside the car it
might change your swr a little but rolled up inside the car which is a
semi faraday cage anyway wont cause any harm.

Jut loop it. Make it around 6 to 8" then tape it together. It will in all
probability improve your swr. Also, if you are 'terrible at working with
coax' you could cause more damage than good.

strictly speaking,if your antenna is properly trimmed, the length of
coax should have negligible affect on swr. Of course im assuming its
not a balanced antenna and therefore there may be other complications.

Default Re: aerial cable

Coaxial cable with no loss whatsoever (doesn't exist) would not be affected
by looping the cable into tight small or large loose loops.

However... thin CB coax is lossy (RG58). Some cheaper coaxial cable is
complete rubbish and can badly affected by being looped up. There's plenty
of this being sold by unscrupulous CB and Amateur traders as 'quality coax'.

Because cheap coaxial cable is lossy its impedance can be affected by loops,
proximity to electrical conductors, etc so I would recommend trimming off
excess cable. And besides it makes a neater job.
