The first thing I thought when I read this was that 45" and 50" we're 
supposed to be 4.5" and 5.0". Are these type o's? I'm not gonna say 
it won't work but most people building a coil with that size NST 
would probably recomend a 4~" piece of PVC pipe as your secondary 
form. Also most people would recommend between 700 and 1400 turns of 
a smaller gauge wire for the secondary. You also state that you won't 
be using a top load. I wouldn't recommend this as you wil probably be 
dissapointed with you're streamers without a topload. The mental 
picture I'm getting (no offense) from this is that you're probably 
new to coiling and this is your first coil. If that's the case you 
can get plenty of advice from the list. The other mental picture I'm 
getting is that you may be a coiling expert and that you're trying to 
produce a coil that's very out of the ordinary. If that's the case 
you're probably laughing at my response.

That seems interesting...

Im not even sure if that NST wil be able to power that coil and
produce any reasonable output?...

Hi All
I am considering building a TC with the following specs and would
appreciate any comments

Secondary: 83 turns #16 ga wire on a 45" diameter by 24" high form
Primary: 2 turns of .375 copper tubing about 50" in diameter
NST: 9000@120 ma
Cap: .035
Synchronous 4 pole RSG
Note that both primary and secondary are resonant at about 250khz.
The secondary will not have a top load.
Thanks in advance for all comments
Skip
