[TenTec] OT: Half inch Andrews Heliax LDF4-50A vs LMR-400

[Bob McGraw - K4TAX]

But is one going to operate at 30 MHz frequently?   Doubtful.  Of course 
loss decreases with frequency.  Anytime I have a feedline total loss less 
than 1 dB measured  {key point is measured not "book" numbers} I'm happy. 
Same with SWR values being less than 3:1.   Usually the difference between 
3:1 and 1:1 is not noticeable on either end.

Don't sweat or freat the small stuff.  It isn't worth it at HF.  Now at 432 
MHz or 1296 MHz I nit picking for every 0.1 dB I can find.

73
Bob, K4TAX
