Learn MoreSome people say the coax shield is part of the antenna, it may be so, but a short ground connection does make a difference, instead of 100 ft/30 m coax shield, as in my my case, going back to the radio room. I installed a wire going to a ground rod at the base of the antenna and the difference, for the better, was substantial.
Learn MoreRadio waves, both natural and man-made, contain electrical energy you can tap using simple solid-state hardware. Radio wave collectors use long, insulated copper wire antennas to drive current to a …
Learn MoreA simple antenna signal booster circuit as depicted in Figure 2 will do the trick if your receiver requires a higher level RF-input signal than what the matching network can produce. The antenna signal booster circuit is constructed around a few transistors and supplementing components. Due to that, the circuit delivers an RF gain of around 12 ...
