[TowerTalk] CAT5E based RX SWITCH for remote RX ANT distribution

[Vojtech Ritzko]

    HI ALL

Our QTH at OM0M  islimited in space and there is not room for extended phased beverage systems.
I am trying my best to build system with RDF well over 14dBon limited space QTH.

(Kill the side lobs and your RX will love you too.)

 
W1FV-9 circle for 4 directions as well as linear 4el inlinesystem for USA were built in field day styleprior the CQ 160.

Well done, but how to connect the hamshack with RX HUB?

 

Single RG6 and CAT5E FTP  cable were directly  buried  undersurrounding road  in past.

 

Initial design - RG6 for RF and CAT5E for relay control isnot sufficient nova day.

No cable duct = no way to extend anything.

The only chance is to use the unoccupied 100 Ohms pairs inCAT5E to carry RF too. 

 

CQ WW 160 was the best chance to test RX systems in toughcontest conditions.
