BevFlex-4X Installation Manual Rev 2.23 November 2019
outstanding results for the reception of weak signals that are otherwise unreadable using your normal transmit antenna. The
key receiving benefit of the BevFlex-4X is not to increase the received signal level, but to improve the received signal to
noise ratio in the favored direction, especially on signals arriving from distant stations at a low elevation angle. All received
signal levels will be lower on the BevFlex-4X than receiving on your transmit antenna, but you will now be able to hear
signals that were buried in the noise on your transmit antenna. “If you can’t hear them, you can’t work them,” even if they
can hear you!
As a reminder, this is a RECEIVE ONLY ANTENNA AND MUST NEVER BE CONNECTED DIRECTLY TO THE OUTPUT OF A
TRANSCEIVER. The application of more than a few milliwatts of power into the system will result in damage, and such damage
is NOT covered by the warranty.
