BloodBlade If the repeaters are placed together, shouldn't the antennas be relatively close to each other? Wouldn't that prevent interference between them? Is it possible to upgrade a duplex antenna into a multi-band antenna using just one antenna?
BG2EWI BloodBlade Generally, this is not a problem. First, the equipment inside the cabinets has iron casings that provide shielding. Second, when installing the antennas for transmission and reception, appropriate spacing is considered in both horizontal and vertical directions.
BH1QAE BloodBlade That's not necessarily true; it's possible for some devices to use 50-meter feeder cables.
BG8AMG The difference in antenna height in the vertical direction is sufficient to minimize interference, and with the duplexer, the three repeater systems installed at a tower location by the Chengdu club are all working properly.
