Hiya, Jack --

   The original quiery was only about the KT34A, not the bigger XA version.
 With a 16 foot boom, it will play similarly to other tribanders of similar
boom length (since gain is a function of boom length.)  Also, the KLM has a
dual-driven element feed so only one driven element is being excited at one
time; hence, it is a '3 element tribander.'

   I'm sorry but I don't have any experience with the Fritzell antennas that
you mentioned.  I have seen the Sommer and was not impressed with its
complexity; is the Fritzell similar?  My personal opinion is that antennas
worth putting up are used by many contesters and that antennas not worth
putting up are not (i.e. lots of KT34XAs and TH7DXXs but very few Mosleys.)
  Let me know if I'm missing the boat on the Fritzell.

Think of it as brake lights!  Even a 100-watter like me can keep certain
Texans off of my JA-running frequency by beaming some of my meager
power SE.  If I split my power in half, I only lose 1/2 S-unit on my main

Subject: Ground conductivity in the desert
Message-ID: <v0151010aad510d580292@[]>

I am appealing to the theorists out there that may have an opinion or two
regarding soil conductivity and its effect on the vertical angle of
radiation for horizontal antennas.

Living in southern New Mexico offers less than 8 inches of annual rainfall.
The soil is sand and rocks. I have been told it is the WORST soil anywhere
regarding conductivity. I would really like to hear from you guys in
Arizona, Nevada, West Texas, Colorado, etc. etc.

Question 1) Is there documentation out there already specifically
describing and analyzing soil conductivity vs angle of radiation? If so,

Question 2) In your opinion, would there be any benefit in building a
man-made ground plane under my towers? If so, what would you use and how
big would you make it?

Question 3) Do you feel ground conductivity is a factor in the 'attraction'
of lightning?

Question 4) Perhaps the most important queery, does it really matter since
the ends wouldn't justify the means?

Please respond directly. Thanks in advance.
