Topband: RX antenna switch

[Milt -- N5IA]

Here I use a basic 8 port antenna selector designed to my specifications by 
a ham friend of mine.  The circuit boards are professionally etched and are 
equipped with chassis mount "F" female connectors.  The single, 8 port 
boards can be daisy chained for 16, 24, etc. antennas selections.

At this QTH the Beverage antennas are remotely controlled via the Green 
Heron 2 GHz system at a distance of nearly 1/2 mile.

Currently the system is comprised of 19 separate antennas, each RF split 3 
ways, with each split antenna selection fed to one of three separate groups 
of three of the above described boards.

Results are at three operating positions each op has independent, totally 
separate control and visual readout of the direction and labeling of any of 
the 19 antennas.

The visual is provided by a programmable compass rose on the computer 
display screen.  Selection is by either clicking with the mouse which 
provides instant, opposite direction selection for an example, or via a USB 
rotary switch for normal step by step selection of the antennas.

I have no connection with Green Heron other than I am in love with the 
upgrade of control capability their system has provided for my remote 
Beverage farm.  It is so nice to have retired the old DTMF and basic CPU 
type controllers and control lines.

73, and good luck de Milt, N5IA

A new computer controlled RX or TX Antenna switch will be on the market in
about a month.  It will control up to 10 antennas or any other contact
closure selection device with the click of a mouse.  Users will be able to
assign GUI designators to each port.  Example for beverage selection the
user may want to designate:
NE, North East, EU, 45 or any other designator of choice...  I have a
prototype at my QTH and am doing field trial now.

Details will be announced on Top Band and other venues.

73,
Jack
