Default Magnetic Longwire Balun: weird resistance normal?

Since this is an SWL group, a more meaningful number would be 15 mHz, and
I'm not sure that a loss of 1.5dB is going to noticable. 5dB would, but how
many people have 100m runs of coax?

Geoff.


You'd be surprised. Even at HF, there are QRP applications where a dB or
2 makes a significant difference.

This is a DC to Daylight group.
