[Antennas] 11 Meter (CB) Antenna Questions

[kg6irh@ftnetwork.com]

Somebody gave me a CB rig today with a mag mount antenna.  The only problem is that
the feed line on the antenna has been cut and needs replacement.  I have two
questions:

   1-Can I use 52 ohm coax instead of 50 ohm coax even though the impeadance
   of the transceiver RF plug is 50 ohm?  What kind of problems, if any, am
   I going to encounter if use 52 ohm coax?  I am thinking about using RG-58 
   coax.  Would RG-8 be better and, if so, how much difference would I be 
   talking about?

   2-Do I need to cut the feed line to any particular lenght for "electrical
   length" or otherwise?  I remember being told many years back that one needed
   to cut CB feedlines to match lengths of nine-feet.

   I intend to put this mag mount on a sheet of metal about one-foot by two
   feet on the roof.  My run will probably be 50 foot.

I know that this somewhat off-topic.  I want to rig this unit up for two reasons:
One, Ive got it and want to put it to use.  Two, I do like to monitor CB traffic for emergencies and would like to be able to contact anyone transmitting emergency traffic.

In any event, I will operate on CB according to all applicable FCC regs such as maximum 5 W ERP.

TNX in advance for for your replies.  73 DE TIM KG6IRH.
