| Reviews Summary for KD9SV DXPedition RX Antenna Switch w. Dual Preamp |
|
Reviews: 1
|
Average rating: 5.0/5
|
MSRP: $269.95
|
Description: Here’s the ultimate unit for the active low band dx’er. Combines the Front End Saver, dual band (160-80 meters) variable gain pre-amplifier and a four-position antenna switch in to one easy-to-use package. Originally designed for DX’peditons, this unit is sure to be on the wish list of all low band dx’ers. Will work with all amplifiers and includes a heavy-duty relay for older style amps. The four position antenna switch will allow you to select four different receive antennas while giving you front-end protection and a variable dual band pre-amp. You can also by pass the unit and use the transmit antenna when you are operating on the higher bands or if you want to use the low band transmitting antenna.
New Improved Solid State Switching design.
KD9SV has redesigned the front end saver with a lightning fast solid state amplifier keying relay. This is a significant improvement to an already state-of-the-art product and will give years of trouble free service. This redesign will work with all amplifiers.

Great for Lowband Dx work

I've been using this unit for a couple of years now, primarily to protect my radios from excessive RF input coupled to my RX antenna input from the nearby transmit antenna. Mine is the older unit that uses a sequence of relays to disconnect the RX antenna, short the RX antenna input, and key the amplifier during transmit.
I'm using it with an Elecraft K3 transceiver, and have found the switching to be fast and reliable, while the selectable preamp provides some needed gain on my puny receive antenna. One of the four selectable antenna inputs is wired to an Elecraft XG-2 RF generator for testing purposes.
