[Premium-Rx] HF Antennas for the city?

[Chuck Urmson]

Hi Steve,

The Wellbrook range of loop antennas are fantastic ( 
http://www.wellbrook.uk.com/ ).  I have the ALA1530 and I hate to say 
this in our group but it knocks the socks off my "premium" Rohde&Schwarz 
HP005 DF Dual Loop Antenna and Racal AE001/A  Active Monopole. 

I live in London and the noise and interfering signal levels here are 
about as bad as you get anywhere in the world.  Loops also work very 
well mounted close to the ground. 

Regards,
Chuck
