rev.1 5/2019 by Jan OK2ZAW '''This is low noise receiveing antenna system for 4 directions in 90 deg angles (can be different, just controller has got LEDs in 90 deg order). This antenna consists of 2 x Bi-dir beverage sets, 4-way antenna switch and controller. That all allows you to have 4 directions beverage system with only one coax line from the field to the controller. Controller have got internal PCB with 3 BPFs, preamp and protections. There is also RX ant switch for TRX which does not have input for RX antenna.'''

Coaxial cables go to middle 4-way (4 direction) switch. * Than only one coax goes to the controller. * '''How to prepare it:''' ** Positions of the antenna in field depends at your possibilities ** If you want to use it in 90 deg cross, than go to next part and select which combination is good for you ** Depends on this configuration you need to select right Jumpers at the Front Panel in the Controller (open enclosure) ** Rear switch at Controller must be switched to 4-way position ** Enjoy your low band DXing :) '''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: There are the common-mode current filters which help you to obtain as low antenna noise as possible. But do not forget to good grounding, not only for antennas but also for 4-way switch.''' !Where are your feeders * '''Everyone has different antenna configuration and also feeders could be on different places.''' * Controller allows you to set right Jumpers (JP) and follows your instalation.
