Hello again,
Thanks to all - Dave, Andy, Bob and John,  for valuable comments.

I probably will never put up some of the huge arrays that you do as I am 
almost always a single op so It's looking good for what I need.
The vertical load of the kr-400 is spec'd at 200Kg, I suspect I'll never get 
this heavy - I'm only a mere 85 Kg!

I'll be using the rotator for the first time this week-end to turn the 2 
metre talkback aerial for the first 3cms cumulative. I'll also put a 
lightweight Moxton rectangle up for 70 MHz as well. Location will be /P 
IO94LI on the N Yorks Moors.

Regards,
Eddie
