Help-SWRs and Coax Cable Lengths
 

Greetings,
I'm installing a Uniden Grant CB with SSB and a 300 Watt Linear. I will
be using Dual Antennas. The CB will be mounted in the headliner and the
Linear under the Driver's seat. The Coax will have to be at a minimum of 10
feet from CB to Linear and a minimum of 10 feet from Linear to the Dual
Antennas. Any recommendations on the lengths of Coaxes or anything about
this setup.
Please send your reply to . Thanks for your time
in this matter.
Sincerely,
Jerry

What I would do is to put your left foot in a bucket of salt water
before you drop the key down on the 300 watts... if that doesn't work,
then shave a spot on your head about 4 inches wide and put a small
salt water soaked sponge to the spot and drop the key again... that
should work great

The duals are a stupid idea. It is a waste of money. It only looks cool.

Bad reasons:
1) the two antennas need to be a quarter wave apart (8.5 feet)
2) you need a co-phase harness, two equal length pieces of 75 ohm coax
3) any length of 50 ohm coax will work to your splitter
4) you can never get the coveted 1:1 SWR in that setup.

Just get yourself a Wilson 1000 or something decent and be done with it.
You will thank me for that bit of info later.

Use 14' rg8x should give low SWR.

Coax length means NUTHIN' ! Just use 3' incriments!

Could you explain this to me? I'm fuzzy on that concept.

Why use 3' increments? Coax length means NUTHIN.
Worthless hick, you can't even spell.
Too many thumps on the head from that bible?

Tell that to my Taiwan, R.O.C. PC-122 that works great
with 7 feet of coax in the mobile. The TS-250 likes it, too.

BTW, I'm still fuzzy on the concept of specific lengths of
50 ohm coax with 50 ohm radios and 50 ohm antennas.

Please enlighten me, Dave.

Try explaining that to the judge...
