The Select-A-Tenna produces a signal gain of +30 dB when used with most AM radio receivers. It's a passive device and requires NO wires or batteries.
It works simply by placing it next to your radio and tuning variable cap control to the same station frequency as your radio!
The Select-A-Tenna concentrates the RF signal energy in near proximity. If your radio has an internal antenna and is placed in near proximity, it shares the signal concentration. The radio's automatic gain control reduces the signal above a threshold level. The net effect is to make very weak signals +30 dB stronger!
This is MINT 541-M, same as original but with 3.5mm "mini" jack allowing connection to a outside longwire and ground. The jack may also be used to connect the antenna to the AM set's antenna input if the radio does not have a built-in Ferrite antenna.
