Signal blocker Jamming Zoom
A large external antenna has strong receiving ability, but signal jammer interference is also greater. Usually, an amplifier is installed, and the outdoor input signal can make the host achieve full power output. Antennas outside the city do not necessarily need very high gain.
Some installers who think they are masters install two outdoor antennas on one host. But I don't know how much interference to the signal. More than 90% of the so-called interference is the mutual interference of external antennas. Many amplifiers with poor indicators have not debugged the output signal at all, only the output power and gain. Checking the circuit board is just a series connection of the filter and the amplifier.
