!How to use this RX antenna switch *'''This is almost classic antenna switch with high insulation. What is more complicated there are the dummy loads, which are there for:''' ** Bi-directional (reversible) beverage antenna with both directions output. [link|https://remoteqth.com/two-wire-beverage.php] Allows you to share both direction through bands and RX. ** If you want to use '''TWO INDEPENDENT RX on each band'''. Than you need middle box - '''Splitter'''. [link|https://remoteqth.com/7ant-rx-splitter.php] And it needs right impedance on the ports which are not used. *''' When you use any other antennas and there is no splitter - than you can leave ports open.''' * Have a look here: '''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: TWO coax output beverage antenna works right only, when both ports are loaded with right impedance on the same band. It means that you cannot leave second port open or short! Also if you use first port on 160m and second on 80m than second port have to have load impedance on 160m and first port on 80m.
