Hi to all, second post (first in intro), looking for some advice on antenna installs.

My 4x4 is used in three ways.

First, running friends to and from functions so just a small minibus.

Second, weekend away camping off road, no roof rack, fridge and other basic gear.

And finally full on expedition prep, roof rack, RTT, spare, fuel blah blah.

I recently fitted an Albrecht AE 6110 CB, fits with some small mods in the space made when the ashtray is removed, I used a mag mount on the bonnet, SWR was easy and worked fine on a recent trip. The issues I had is the canyons where we were are very narrow and the foliage very unforgiving, it often snagged the Ariel and pulled it off, and some reception issues from vehicles behind, the rack and other gear probably killing the signal?

So, I fancy having two options. A permanent quick antenna release for the Ariel on the panel at the bottom of the windscreen, further in from the edge so less chance of being snagged, and another quick release on a metal plate mounted on top of the roof rack. And then have just the one Ariel that can be removed when running around during the week, and then fitted to the car or rack depending on planned trip.

The roof rack could be earthed to the body but I fancied one of those that have the false ground plane, but then is there one that has a quick release base?

Am I right that if I 'Y' the two cables into one and then into the radio, I may have trouble getting the SWR right, i.e. one quick release no Ariel, and one quick release with?

Or run two separate cables and only connect and SWR in the relevant one, or some kind of simple change over switch, which is my preference.

I am not a complete noob with CB's but it has been a few years to say the least so go easy on me.

TIA

regards

Dave

Antenna switcher is the best way to go , If you can leave both antennas on then you will need a Co Fased harness to run 2 antannas at the same time .

Thanks for that Dragonfly.

I am doing the sponge thing at the moment, soaking up and cramming 'CB stuff'.

I will not be running two antennas at the same time, the roof rack gets dropped on just for the longer trips. As time was short this time I went for the mag mount and of course the coax got beaten up, the canyon brush pulled at the whip, so looking for something a little more permanent. So weekend trips no roof rack, antenna on panel below screen, longer trips with roof rack (I reverse into garage and lower it down on to the car), :wink: That means the antenna can go up to the roof, less chance of damage and no blockage 'aft'.

I do like the idea of a switch between the two, just a bit worried I might key up with the switch in the wrong place and fry the set? :cry:

yes the coax switch is the best way to go and a big notice over the speedo to remind you

Still 'cramming' in the CB stuff, when I get into something I am like a dog with a bone! :D

I have now changed the plan, or rather others have changed the plan by coming up with good arguments to do so. I am trying to draw from different CB forums to get as wide an opinion as possible.

So, one panel mount on the roof towards the rear, there is (or will be) a hole that is unused. That will have a quick release and spring. Next the roof rack, the rack is a full length type, RTT and all the usual stuff up there. Another panel mount but unsure if it is going to be front or rear. I am looking around at the moment for a thru panel mount that can be quick release. The plan (at the moment), is to be able to use the QR and lift the Ariel off, and lower the roof rack into place. The roof rack will already have the QR attached and the cable waiting to be connected.........but to what? Is there a thru panel connector that I can just screw onto? Something that can be made waterproof when not in use, i.e. when the rack is off.

Once the rack is mounted and the cable is connected to the car, I can just climb up and clip the antenna in place, turn the control on the coax switch and off I go.

FORGET the quick releases as the spread at the base and can give a faulty swr reading so are not very good

Thanks for that Stampman.

I have been looking into that as well, what about high quality SS versions like this, have you tried them?

http://www.a1telecom.com/theshop/catalo ... isconnect/

I have an underground car park that the 'cruiser' lives in, very low so the ariel must come off and on a fairly regular basis, PITA but the only reason for the QR as it seems quick release for a cable is not avaiable.

There was also another heavy duty QR but cannot find the link, it does seem one of those 'you get what you pay for' scenario's?

I may have found a solution!

One cable running to a disc type mount, it seems there is a COAX connector can go on top? Unsure at the moment if the seller and I are singing from the same hymn sheet but it looks good ATM.

Get back to you if it pans out.

a longer version would be a firestick and very heavy unless it was fastened at the top to the air deflector it would destroy the mounting in the cab
