hi guys,

I have recently installed a new tx 3440 and using a gme 409l 6/9db antenna problem is that when using it i can get perfect reception upto 1klm after this range i cant hear anything? Can some one help with reasons why i cant get any range?

I was told when i cut the coax to fit into fire wall i might have stuffed up the capping of it? would this cause a dramatic loss in receiveing signals

I thought the length of cable on an ariel was the length it should be for good reception.
If you cut it , it may not be the same length.
Mine was pretuned for the ariel when I bought it.

You may have shorted out the co-ax when you re-terminated the PL259 plug. Or the centre wire is broken. Cut the plug off, and start again.

Yep - the local UHF experts told me up to 6m of coax should be trouble free with modern UHF's. Re plugs -I'm a bit of a techno klutz but I test the circuits in the coax (both centre and shield) once the plugs are on, prior to connecting it all up - a cheap multimeter etc can tell you if you have stuffed up somewhere, before you do any damage.

I had the same exact experience and it was one tiny strand of the outer wire shorting when I fitted the plug. Re-fitted the plug and it was all good.

Hi there,
I have the same set up. be carefull when fitting or removing the aeriel. if you use the black base to twist it on or off it can break the internals of the aerial.

Plug on the AE409L is not designed to be re-useable. Buy a new plug and have another go :-)

thanks everyone,

Have replaced the existing plug and its amazing wht the difference is. I can now get 20klm line of sight on all channels and atleast now can use repeaters.

I checked the plug with a meter and instead of staying as a open link it showed 0.1 which i found out means it has a short! lol :) and whould have been extremly lucky to have got 1klm. Wish it explained these things happen when you install them rofl

cheers,

tycune
