Hey Buddy!! Long time no hear!!
Last time you popped up, I was working on my KT-34a. Long, Long, time.
15 years, at least.
Take a look at the pics. 28 of 42 elements are mis cut. What's more, 9
mistaken pair are adjacent and 1/16" different. This leads to the
wrong element being the right size or the right element being the
wrong size!! Confuse-o-rama!!!
So how does one build an antenna with 42 elements when more than half
of the element measurements don't reflect the instructions?? Not
possible. I guessed putting it together based on the pattern of
elements. The antenna is a match at 50 Ohms. As I've said, the rest of
the performance parameters are anyone's GUESS!!!
Any guesses about performance from this antenna are just that,
guesses. Modelling will only get you so far. As I'm sure you're aware,
what happens in a computer model oftentimes is not what is seen in the
real world, i.e. antenna range.
Again, look at the pics. Any questions? Look again. I have a receipt
for almost $700. It does equal that amount if I add the round trip
tolls.
So for $700 I get an antenna that's 50% wrong and unable to be built
without guessing? I bet you'd go for that!!
