[CQ-Contest] Re: Topband: TOP BAND RECEIVING ANTENNAS

>but efficiency too low compared with low signals.

Low band receiving antenna efficiency is limited by outside noise 
which should be received some 10 dB stronger then own RX noise.

This is very easy to achieve with any of the present solid state RX 
but some hams prefer additional preamps...
