Jim, I, too am using the LMR-600 running 160 ft to the tower.  I will use
LMR-600 Ultraflex from the tower base to the to antenna which is at 65 feet.
My tower is a One Man Tower imported from Australia.  Built like a Brick
s--- house.  My antenna is a 4 element Steppir with the 40/30 element
option.

Installation not completed yet.

Mike, any idea on how your R8 performs vs. another vertical, say a ground
mounted type with radials?  I think that would be very interesting.

I have a couple of R8 Verticals that are elevated and they work pretty well.
The do not require any radials.  Most other verticals will require radials.
Even the BigIR requires radials.

Actually - the report that K7LXC did, is a good, well written report, with
good experimental data to back up the claims.  It certainly helped me make

I don't have any other verticals to compare it to.  I don't know if the
publication K7LXC was citing includes the R8.  I worked plenty of DX with it
this weekend but I don't have anything to comapare it to.  I am surprised by
what I can work at times though.

Yes, it does include the R8, but it wasn't elevated much and there  
was a ground screen.  Based on the results quoted, I was seriously  
looking at the R8, but the AV-640 is nearly identical except for not  
using traps and I went with that.

Steve and Ward's yagi report is also excellent.  I worked on antenna  
ranges for many years in the aerospace industry and couldn't find  
anything to fault in their test methods.

Interesting thoughts.  I NEVER ran any Polyphasers etc on my rotor  cables.

Everything was disconnected at the bulkhead by Cinch-Jones  plugs.
Amazingly 
even though I had lots of rotors on the 200 foot  towers, I never had a
rotor 
failure from a lightning hit...mechanical  damage from wind etc, but no 
electrical problems.  My gut feeling is there  are few direct hits on the
rotor 
cables and most of the damage from  non-disconnected stems from the induced 
voltage of the hit and perhaps providing  a great ground for the main
lighting 
charge to travel to ground through the  house mains by way of a short,
jumping from 
the tower or coax to the  cable.

Hi Gang,

  I'm looking for two strands of Andrews LDF4-50A (1/2" hardline) of about
110'
each.

  Anyone have some lengths laying around, not being used?

Is LMR600 or the equivalent too stiff to pass through three 45-degree sweeps
in a 4" PVC?  How about with an 89' crank-up tower?  I am trying to decide
whether to reuse my Davis RF Bury-Flex or replace it.  This antenna, a 4L
SteppIR, will have 6M on it, and I've never had to be concerned with
attenuation for that band before.

I don't disconnect anything since I finished the ground system installation.

That's mainly because the connections are too difficult to get at and the 
storm would be past by the time I could get them disconnected.

Since the ground system was finished I've had no damage yet the tower takes 
at least 3 direct hits on average per year. It was five the first half of 
this past summer.  I say at least as those have been observed.

IF I recall correctly Tom said he didn't disconnect anything either, but 
I've only seen one post from him in recent months. I understand he's over on

the amps reflector.
