Steve and all......... I just happened to have something similar here that I
could go test. Instead of the coax going/continuing in a straight line, mine
doubles back. Think of the "Victory" V sign with your 2 fingers. The splice is
at your knuckle, and your 2 fingers are the coax going to whever.....
I had abt 65' of RG213 to the splice, and then abt 35' past the splice to the
end. I placed a 50 ohm resistor at the end and ran it with the MFJ-259 (after
of course checking the resistor right at the 259 to make sure it was a "dummy
load".
Up to abt 7 or 8 mhz, little or no variation 1:1. Then as I kept going up to
30 mhz, there were little spikes to abt 1.3:1. Going up to 50 mhz started
getting spikes to 1.7:1. Now I would suspect some of them were cause by 1/4 or
1/2 wave lengths, coax age, my "old" eye sight, and a few other things we won't
go into.
Of course, as always, YMMV.
I used this coax/splice this winter on a quicky 75/160 vertical I threw
together. Worked way beyond my wildest dreams!!! 26' tall (boom from an old
204BA), 9' top hat, some well placed inductance, and 24 ea 30' radials. 600
watts PEP out.
ARRL Intl DX contest...... in 24 Q's, 4 were Canada, the rest were Europe and
Central/South America. The 1st was with ON4UN...... Talk about a thrill!!!!!!!!!
CQ 160/SSB contest had 100 Q's, all over the US and Canada.
Can you tell I'm a real hard core contest kinda guy?!
Hope this helps a little.
