A Supplied Aerial Test

[the_top_pilot]

PAW Friends.

I use the aerial supplied with the DVB-t Unit and am really happy with the range.
This morning in a bored moment I unscrewed the top section of both my PAW unit to see what happened.
The answer....... Not a lot.
From My Home in Ruislip West London (the rear of my house faces 320 degrees) I am able to receive aircraft (at altitude) upto Leicester and East Mids. with the aerial element taken off i was still able to see aircraft at Oxford.
as my aircraft only flies at 108kts I may now leave the top element off.
I would be interested to hear anyone elses results for a similar test

I did a similar test a while back for receiving VHF on one of these dongles as an SDR. It seems that at least for VHF, the majority of the signal picked up is through the coax.

However I bought a larger antenna with some curly bits on it (!) to try with the ARF, but I tried the antenna screwed onto the DVB antenna base - and it does bring in traffic from further away. However we're talking 100-150 miles here, so it's not really needed for collision avoidance where, as noted, a wet piece of string will do the trick! Or at least a little stubby antenna.
