that landrover question again

[philbert]

hi all.
having problems fitting a twig to my canvas roofed landrover.
it seems anywhere i fit it i cannot get the swr down its normally of the scale!
is this because its alloy bodied or because im not getting a good enough earth on the mount?
its a sirio hypower twig with so239 thru body mount.

help please

TEST THE CABLE FIRST NO SHORTS AND CONNECTION FROM 1 END TO THE OTHER

[philbert]

yep checked the cable no shorts and connection from end to end

[stampman]

check continuity between antenna and pl259 at rig end if its a ml145 then you should have a short on the cable

[philbert]

have just checked with a ml145.
i get continuity between the whip and the centre and the outer of the pl plug.

[stampman]

check the patch lead and make sure the swr meter is in the correct way i haveconnected them up wrong at times

[philbert]

the patch lead is fine no shorts.
the swr meter is working fine if i connect up a mag mount i can swr it in no probs.

[stampman]

check mthe mount although if you are getting a reading then that should be ok if the swr is higher on 40 then chop a bit off the whip if its higher on 1 then its an earth problem

[philbert]

Thanks will go and try re mounting the twig and start again .

cheers

i was getting a bad swr on my hardtop 90, so ran an earthwire to the rear xmember, and its fine now.just used a piece of amp wiring from a car soundsystem (the red stuff)

[philbert]

tried that before with a jump lead to the chassis but it made no difference!

Was expecting problems last week when I fitted my first cb & aerial as I was away for the weekend and was desparate to try it out.

Get yourself a military roll bar under the tilt and mount to that, mine perfect so far (fingers, legs everything crossed)

[philbert]

got it sorted just drilled a hole in the front bumper and fitted it there!
works a treat wont do much for distance though !
but then again its only for use when im out with mates so distance isnt needed

good another happy customer
