Dear folks:
Interesting how this gentleman was apparently waiting for a chance to expound
on
this subject. I did anticipate that, of course - in fact, I was told beforehand
because of some history in this area. However, I did choose to make a specific
reply to Mr. Soper. I will make one in regards to Mr.Tony Brock-Fisher.
It is nice you have so many hard-felt opinions. You sure like to create
subjects
to talk about, whether they are relevant or not. I believe your first paragraph
might well characterize your entire reply.
Your comments about the original poster not mentioning the antenna being
specifically used for a DXpedition is a bit odd. Don't recall Mr. Soper saying
that at all and neither did I. It happens to perform that task that very well,
though. Your comment in the same paragraph regarding "low height, near or over
water, the longer boom length of other antennas would not be effective" is not
correct either. I think almost everyone knows this.
Longer booms usually imply more gain and if the (Yagi) antenna can't be very
high, then more gain is a great alternative. The increase will cause vertical
lobe compression (compared to an antenna of less gain) and emit more energy at
lower angles, which is what we usually are searching for. Utilizing a vertical
track test site verifies this situation - even the software will show the
improvement on a comparison, with a rectangular graph being a good tool for
this
purpose.
That's all. Have other things to do, like figuring out how to find true North.
I'll check tonight to see if the North Star is still in the right position
tonight!
Hope all you fellows make it through the VK0 pile-ups. It might be tough on the
low bands.
