Radioman:
If you can deal with some questiosn from a neophyte SWL'er using a TenTec RX 320 I am "apartmented" and am Using stealth antennas, short random wires, slinkies, verticals, and wonder if such a device will be of benefit. Is it redundant or conflict with with the active antenna of the RX 320 (I'm told it doesnt function unless RX 320 whip is in service...it isnt) Current antenna uses home mande 9:1 balun ...will it have to be shunted for the MFJ 1040B to work best? My Goal to enhance signal strength and seperate overlapping signals Yodar in orlando (a LIVE one!) Radioman wrote: The MFJ-1040B preselector boosts signals from 1.8 to 54 MHz. It utilizes dual gate MOSFET, bipolar transistors for low noise and high gain. Push-button switches provide for two receivers, two antennas, 20 dB attenuator and ON/BYPASS. The band switch selects: 1.8-3, 3-6, 6-15 and 15-60 MHz. Controls for Delay, Gain, Band and Tune. Unlike most preselectors, which are for receive-only, the MFJ-1040B may be used for transceiver. It has a relay that automatically bypasses the amplifier when transmitting. It can handle a transmit signal up to 350 watts PEP. Rear panel jacks provide for the use of either RCA phono plugs or PL-259 connectors. Size: 6 x 2 x 6 inches. Comes with optional 12 VDC 300ma AC Adapter. Works perfectly but has some scratches on top. Asking $75 which includes shipping to CONUS. |
