Default Yagi efficiency

Rick my call is KB9MZ My antenna which is not of the Yagi design has a
TOA of 10 degrees and hopefully will be up before the weather gets to
cold. I am restricted in height to 120 feet So as you can see I am
pretty well committed to what array I am using. But the initial
posting was not about antennas per se but about the efficiency of the
Yagi with respect to desired radiation. Some would have you believe
that radiation
which is not within the main lobe is miniscual so I suggest you imagine
two models one of which has all lobes removed except the main lobe Do
you feel that both models now need to be labelled to avoid confusion as
they look so much alike?. As for other side comments regarding TOA I
suggest one reads the post from Mac which I whole heartedly agree with
(Thanks Mac, tried to get in touch with you a few months ago but E mail
was rejected)

OK, so I've read all of your posts, and all of the replies, but somehow,
I still don't know where you're trying to work Europe from....

Maybe I'm dense, or can't comprehend the previous posts, but the best
I've been able to find is that you have a 4000 mile path. Still, that
could be quite a number of locations, given a 4000 mile circle around
europe, though it may not really make much difference...

What bands are you trying to use?
Where are you located?
Why are you so concerned about high angle radiation? The vagarities of
multi-hop propagation often provide some really interesing contacts from
high angle radiation...

Please provide actual information, instead of vagarities...

Thanks

Hans, you are so full of it, like Andy Capp waving his hands around in
the air to
vent his fraustration. Go back to the initial posting and what it says.
All of your comments refer to side issues brought up that are not
relavent to the initial question
wthich also is not a guessing game to those skilled in the art

You are right... You are so far ahead of this group that we can not
even comprehend the question...


Denny,

This is all apparently intended as a guessing game, as art has given us just one
single parameter of the exercise --- he wants to communicate with the UK in the
winter.

From where?

At what time(s) of day?

On what QRG(s)?

What construction constraints? (budget, zoning, etc.)

73, de Hans, K0HB
