160mt riceiving loop antennaTune C1/C3 until impedance at connector is resistive at 1830
80/160m Small Receiving LoopA small receiving loop helped; it has very deep nulls and made listening on 80 and 160 more pleasant
80m Frame AntennaCut the tubing into 900mm long pipes and drill 5 wire guides 3mm dia through it see drawing

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
