I have a few questions which I am hopeful that the gurus can help me with.

1. Using an rf-choke at the feed point...How many turns and what diameter?

2. Where can I get 200-500feet of 75 ohm tv cable cheaply?

3. Vertical element about 100 feet, 3-4ft from the tower and horizontal 
component 35 feet 3 away from tower....I was told to use elevated radials tuned 
in pairs. I tried tuning each pair as dipoles, starting at 135 feet, each half 
and cutting off about 10 feet from each. Never really saw a dip on the mfj 
analyzer. SWR in the shack is 1:3. I think my 135 ft L might be too 
long......Question: Am I in the ball park with what I have done? I did work 
KH6LC and VK6HD and several zone 3's in CQWWCW easilyand had no problem 
breaking the pile-ups to the carribean, but it just doesn't seem to play well 
to EU. Of course it could have been a high angle night when I tried.Any 
thoughts?

4. The 500ft beverage should go up after the 10m contest. It will be 10feet 
above ground, terminated at the far end. Is 10 feet too high?

Thanks in advance.
