Incidently, The carbon one I got of ebay was a cheapy. Well under £10.
I am not the greatest authority on radio waves but I am led to understand that its not the length of the ariel
but the anteni inside.
Obviously the stubby has a coiled one.
The way to test is on talksport as that broadcasts on the same frequency over most of the country without a need to retune.
When i go to Abbey I cant get jack squit on any channel.
And thats from the Coulsdon Roundabout of M25 all the way to Abbey and back.
I did get it with the OEM, so if anyone does go to Abbey and get good sounds, could you send a picture of the ariel
and where you got it please!
