Hi all,

I have a Maycom ar-108 scanner that i have been using to listen to aircraft. I have recently bought an external antenna and mounted it on the roof. The thing is i cant pick up anything. not even the stuff i can with the rubber antenna that came with the scanner. I have tried it on the local moors before i fitted the antenna and it worked fine there. It also worked fine all the way home in the car until i was on my street. With the rubber antenna i get a signal strength of 5 and pick up the local airport. with the external antenna i get a full signal strength but just white noise. There is a large transmission antenna on the hill above my house which looks like an electricity pylon bristling with aerials and dishes. I presume this may be the cause, but then why is the rubber aerial ok. If this is the cause is there anything i could get that would block out that interference.

Regards

Prophead.

Could be the proximity to the tower coupled with the added signal strength of the external antenna is overloading/desensing your receiver.

You in the UK ?
