Hi Joe

Yes, i know, there are many odds againt it beeing a perfect antenna. But 
that how it is with this super limited space. But what im going for is some 
vertical radiation, to get some low angale radiation as alternative to the 
dipol who has some limitations when it comes to DX.

>>Yes the distance to the tower has influenced the matching a lot ...
