you guys are stalkers!

but, I was never expecting a complete answer. I think I have enough
to get somewhere on my own so I thank you all.
I'm going to work on it tomorrow and I'll let you know how it goes.

I am not in this field, I have a bachelors in electronic
engineering--from decades ago, but never used it, monetary avenues in
other directions lead me far afield ...

My most recent degree is in in software engineering, and this is where I
have worked the last few of decades+ ... I would assist, but like you, I
am a student--of the hobby--and here for my own
enjoyment/recreation/etc. ...

However, I would suspect J. Mc Laughlins' offer is real and quite
WORTHWHILE (in the above post)--if I were you, I'd take him up on it,
you will do as you please.

But, I'd say Mc Laughlin is your man ...

Warm regards,
best of luck,
JS

Dear Richard: He is a senior EE student at Michigan State University. I
sent him an E-mail message offering to assist.

Dear Richard and "s.g.hatch"

I am late to this thread. Apparently s.g.hatch is in Michigan, though I
did
not catch a hint of his location.

What references about Helix antennas have been studied? Prof. Kraus' book
Antennas (third edition) will be in any technical library and the subject
is
dealt with there. Google is also your friend.

If I receive an E-mail with contact information, I will try to help
s.g.hatch. 73, Mac N8TT

Hi Mac,

I read the headers in posts (they are typically hidden to the casual
reader). I can also cross reference the IP address in that header to
a City and State. Our student's location is some 60 miles south of
where you sometimes post. Let's call it a SWAG that he is attending
the University where you are. ;-)

I cannot say that I have been a complete or reliable source, but we've
managed to cover some of the fundamental concerns and it didn't seem
appropriate to finish his semester project for him.

Hey;

We were able to get the input impedance of the antenna down to 45 +
j15, which means an SWR of 1.6. Not too bad I think.

We used one of these http://www.cebik.com/trans/ser.html with a Z02 of
125 ohms.

Thanks everyone for your help, I'm sorry I didn't have time to
implement any of your much cooler suggestions!
