CB dipole from truckstop parts
I made this dipole using 2 side mirror mounts and 2 4 foot firestiks. Swr on ch 20 is 1.1

Re: CB dipole from truckstop parts
I initially wanted to do horizontal but I'm thinking vertical with a Pvc mast to get it just above my roof peak

Re: CB dipole from truckstop parts
If you mount it horizontally you lose benefit( Aka DB) as the vast majority of CB communication is vertically polarized. If you mount it vertically you need to bring the feed line directly out perpendicular to the antenna for just over 9 feet(a quarter wavelength) or it will blow your radiation pattern.
I'd consider using a single vertical with multiple radials ( or a single counterpoise) coming out from the sides.

Re: CB dipole from truckstop parts
I am planning to use the pvc to push the coax out some but it won't be nearly 9 feet.

Re: CB dipole from truckstop parts
I am planning work out how it's fed still. It may be possible to get it pretty close to 9 feet out. Probably at least 6.
I purchased a 102 steel whip for my mobile but I'm planning a base antenna using it and radials.

Re: CB dipole from truckstop parts
let me know if you need guidance. Antennas are one of my specialties. Next time you see me at roosters, remind me to show you my fishing pole antenna I used to contact Martinique.justang1997 wrote:I am planning work out how it's fed still.

Re: CB dipole from truckstop parts
I really need to make a roosters meet
Any ideas on making a "strain clamp" or "cable snake". One of those things to keep strain off antenna feed point from pulling on coax.

Re: CB dipole from truckstop parts
Never bothered with it. A good soldered PL-259 on quality coax (LMR or CA400 from Copper Electronics) ain't going anywhere.justang1997 wrote:I really need to make a roosters meet
