I have the DX Engineering 8 circle receiving array sized for 80/160m . It has been a fantastic performer but I have suffered damage to the active antenna amplifiers on two separate occasions due to
Hello Mark: Installing diodes can cause severe problems with nearby broadcast stations. During the summer months and lightning months I remove my preamps from the antenna elements to protect them. I

GM Mark, The easiest way to think of this is Diodes = Detectors; with high-powered RF around, that becomes a Bad Idea. A possible alternative MAY be high-value resistors to ground across the front en
Ive had good luck using fast zener diodes in series with ordinary small silicon diodes (eg 1n914). The zener keeps the signal diode out of the antenna circuit until the zener breakdown voltage, say 1
Hello Mark! I have the YCCC Hi-Z spaced at the compromised 60 ft. parameters to improve 80 & 40m operation - that was a mistake! Go with the recommended 160m spacing. I plan to modify my Hi-Z for opt
Hi Folks, The Hi-Z Antennas brand amps already have a path to drain static as they are designed to produce 4 to 5 Volts DC on the element with an internal voltage divider. Attaching another resistor
