A couple of messages to me privately about what is high and what is not.
When we are talking about REAL high for 10M, I think you are talking 160' or
more over flat ground. Maybe LPL will confirm or deny.
My station is on a hilltop that drops 250' in all directions quite fast
(steep). My HIGH 10M yagi is at 125'. Just a guess, but I believe it
thinks it is REAL high.
More data points taken today... 3 antennas tested, all were HG105CA's.
1. 5/5 @ 50/25
2. 5 @ 125
3. 5 @ 25
I checked with about 5 SE stations. Everyone in south South America (PY,
LU) said that the 5/5 was the best antenna, the high 5 was 2nd, and last was
the 5 at 25'.
I check with two stations in the carib, and both said that the 5el at 25'
was the best (by far), the stack was 2nd closely followed by the high 5
element.
I also observed that the HIGH antenna was much quieter than the other two
antennas. I noted that K4ISV and NQ4I also observed this on their high
antennas. I had not read anything about a super high antenna being quiet
before this discussion. I wonder if LPL and others with SUPER high antennas
for 10M could post their observations?
Lastly, it is interesting to me that so far I can not find a time where the
HIGH antenna is the best one. I'm sure this will change with more tests.
Last year I did very well with just that one antenna at 125'. It looks like
I should improve on last years results.
