[Amps] Line Sections As Plate Lines

[JMLTINC at aol.com]

Hi QRO gurus -

Let's talk 1/2wl plate lines. 

If you check out PA3CSG's website @ www.qsl.net/pa3csg , or PA7TA's site @ http://www.pa7ta.com/144MHz_RF-Deck.htm , the plate lines on their 2 meter, GS35B amps are about 20.8" (53cm) long.

Everything I have read regarding 1/2wl plate lines says to figure the length for a shortened 1/4wl line (the inductor), and then add a full 1/4wl to that. At 144Mhz that makes a total length of about 28" or so.

I cannot believe their shortened 1/4wl line (inductor) is only 3 tenths of an inch long. Obviously, I am missing something here. Please help!

Thanks in advance-
John, N9RF
