Walking the Beverages used to be fun but here what used to be a hay
field is now overgrown in waist high heavy tropical grasses, cactus, and
huge boot piecing thorns not to mention sink holes and fire ants.
With 8 Beverages I had to find a better way to see if everything was
working. So the obvious checks such as F/B checks with BC stations or
recorded signal reports is the first step. If the East Beverage on the
90 degree BC Station is stronger on the the NE or SE Beverage this is a
good sign something is wrong. If a Beverage F/B has disappeared chances
are that the termination is zapped......or you can check the loop
resistance via the feed end to ground and expect something in the
vicinity of 500 ohms with a 470 ohm termination.
With the MFF 269B I can run a check from the shack which is a real feel
good quick test before a contest. I simply plug the RX antenna cable
which runs from the various switch boxes in my MFJ-269B Analyzer and
switch through all the RX antennas. When they are all below 2:1 (most
are least than 1.5) then the need to worry is reduce. This way I have
found bad splices, rat gnawed RG-6, open terminations. etc.
Knowing that something is wrong and starting with the obvious before
heading into the savanna with a repair kit can be a real saver of time
and effort.
