160mt riceiving loop antenna
Tune C1/C3 until impedance at connector is resistive at 1830
80/160m Small Receiving Loop
A small receiving loop helped; it has very deep nulls and made listening on 80 and 160 more pleasant
80m Frame Antenna
Cut the tubing into 900mm long pipes and drill 5 wire guides 3mm dia through it see drawing
A Crossed Field Loop Antenna for 3.5
This antenna is the latest form of CrossedField Antenna.The electromagnetic wavesare created within the small FieldInteraction Zone around the two
