However, it is important that the antenna is erected away from buildings and sources of interference. The K9AY only requires an area of 9m x 9m to complete the erection. Thus, it will fit into most gardens.

The two-wires in a double-wire Beverage act like the two wires once found in “landline” telephones conducting two signals without them interfering with one another. This is accomplished by one signal being conveyed via “differential mode” while the other is conveyed via “common mode”. 5. WebTo get the antenna in the field to show R=75 on the analyzer, I used a small trimpot of 100 ohm and turned it until R=75 on the analyzer. Measurement was done directly at the base with a 15cm short 75 ohm coax. Fine tuning of the resonance frequency can be done by changing the tilt of the topload wires. Receive 4-square vor 80m.
