[Antennas] HyGain TH-4 documentation

[Robert C. Beach]

I just became the proud owner of a 4 element yagi by HyGain.  I'm 
guessing it's a TH-4.  And so, I'm searching for anyone who might have a 
set of documentation on the TH-4 that could be either copied or 
scanned.  Tnx  W8LCZ / ZD8RB / FO0RB
