Topband: Magnetic Receiving Loop 160m

[Petr Ouředník]

Robert,

try to check the receiving loop antennas as follows: 

- highly recommended is K9FD version inspired by ARRL Antenna Book (i.e. 1982) at http://www.ok1rr.com/view.php?cisloclanku=2004122907

- another one shielded rx loop at

I used for mni years own ver. where the loop was made by aluminium tube 1m diam. only with 5 wounds of isolated wire inside in parallel with 1500pF variable cap. and FET pre-amplifier. Even so small loop had significant bi-directional diag. and good S/N ratio.
