today testing out some old cb antennas. try as i might I couldn't get them to match
after about three hours I finally got up and got a couple beers, While downing the second one it hit me
Remembering my radio classes 40 years ago I remembered the teacher saying" Any transmitting antenna requires a ground
plane equal or slightly larger than the transmitting element to match impedance:

finished my beer and as an experiment used an old 35 inch car radio antenna with a nylon disk as insulator. Then made (5) 7 inch radial elements wired together and bent downward at a 45 degree angle,
mounted it on a fence post away from the house and connected the coax.

Lo and Behold swr tested the junktenna and you guessed it (1.2: to 1 swr) damn near a perfect match

must be the beer jogged my brain cells awake.
I sure am not going to forget that.



kind of makes me want to try ham radios

Eureka moment

got the new firestick firefly antenna (white) just waiting for the mount I ordered, which should be here in a couple days.
anyway a trucker friend asked why Im setting up the cb in my vehicle, and I responded "I'm fire police and sometimes we have to close down roads due to accidents and Its nice to give you drivers a little advanced notice so you can choose another route"

he shook my hand and said god bless you for thinking of us!
sure is a lot easier than trying to turn a double trailer around on a narrow road!

love it

Got me a CB Kit for my daughter's Jeep JK Rubicon. Got the Firestick installed and the cable routed. Also came with a Cobra 75 handheld CB Transmiter. Nice how tech allows you to shrink devices.

Got the kit from here.
