[Elecraft] KAT500 antenna selection

For gosh sake, there are published specifications for the KAT500.  Page 
2 of the manual.  If you are trying to use it outside of the published 
specification then you are accepting the role of a very under paid 
design engineer.    Talk to your boss about a pay raise but don't blame 
it on Elecraft or the KAT500.

If it doesn't do what you need and your needs are outside of the 
specifications, then one needs to ask "why did I purchase this item?".   
The fact it does not cover 630 meters is understandable and is not a 
fault of Elecraft or the KAT500.   The frequency range covered, per the 
specs, is 1.8 to 54 MHz, continuous.

I have no sympathy, patience or understanding as to why someone wants to 
use an item outside of the design specifications.  It just makes no 
sense at all.  I often say if one wants to know where the issue lies, go 
look in the mirror.
