swr meter
« on: January 13, 2009, 20:51:55 »
Hi does anyone in Solihull or Birmingham have a SWR meter I can borrow, or even better meet me and show me how it works aswell. I want to check my CB is working as well as it can.

Sorry to hijack your thread, but once you have an swr meter how do you go about tuning your arial.

How would you know you needed to do this?

For instance, I sound distorted to everyone who hears me but they sound fine to me. Could my rig need testing?

Also, I have a mag mount base and a mini springer aerial, is it the mag mount where the tuning happens? The aerial just screws in, there's nothing to adjust.

You adjust the whip by cutting bits off until the SWR reading is right. Running a rig without doing this compromises the rig and causes its early demise.

I know very little about CBs aswell, just know the aerials are tunable so figure that it would be wise to do it seen as it is a possible thing to do.

Stu.

The whip is the main section of the aerial. It should be detachable from the springer by a little grub screw. You take it out and cut it down until the aerial has an acceptable SWR.
