I found out what the problem was! The dish itself was in the antenna
circuit thus the dish was part of the antenna and receiving omni.
DOH!
I have discarded the dish experiment
AWWW, i would have loved to have a rotatable dish for 160m!
David I still have that rotatable form for top band! I just gave up on
large dish experiments! As I stated I like the idea of small and light
antennas so I am keeping to those root desires. I am getting older so
the idea of climbing towers has to be adressed. Thus as an engineer I
solved that problem, now antennas where the height is not a necessity
for low take off angles! I now have to find out what the greatest
distance can be by substituting one skip for the presently used two
skips ie min TOA.
Since there are not the usual sun spots one has to be inovative and
devise means around it. I can still add a dish ofcourse but I like the
idea of a pencil beam as it will add more gain to that single skip
action. You really should get off that couch and figure out how you
are going to handle a poor sun spot cycle. My cctv rotator will never
be able to handle such a design when tipping is required as the weight
would overcome the motor and it would point into the ground, they are
built for just a small camera not a tank. By the way the antenna is
good for 2 meg upto 170 meg which are the range limits of my MFJ 259
meter. My guess is that it is good for broadcast band upto a giga or
more. Did you fall down?
