Tnx to all who responded to my guy wire spacing question.
I have wondered how important it is to stack similar antennas or if it
does not matter at all.
If I wish to stack 3 15 meter beams, how advantageous is it to make sure
that all three antennas are the same design, boom lenght, manufacturer,
match etc.?
For example, does it matter if the bottom one is a widespaced 4L
Cushcraft on a 27' boom with a gamma match, the middle is a 5L Hygain
155CA and the top is a homebrewed 4L on a short boom with gamma match?
Ideally I would like the amplifier loading to be roughly the same for
all combinations of antennas so do I need to make sure that all are
identical or is the most important thing to make sure that they all
resonate about the same frequency?
What happens if I wish to have two resonant about 21.05 and the other
resonant at 21.25? Does the difference in resonant frequency screw-up
the overall pattern and loading when in a stack?
I know that these sound like basic questions to many but I feel it is
better to ask and give the project lots of thought BEFORE anything gets
bought, built and put up!
Thanks for your help.
