[Boatanchors] Slightly, OT: MF-HF Coax cable loss with high SWR (long post)

[Phil KO6BB]

Thanks Ray,
It appears that the question has been answered for me.  I went and 
retrieved the plastic storage tub where I keep coax etc out from under 
the front porch, figuring I'd use the 213.  In the tub I found another 
unused roll of 213 without connectors that I forgot I had.  It was 
labeled at being ~12 feet long, but in measuring it found it was 
actually 23 feet long.  When I labeled it I must have just 'guessed' the 
length ;-)

Anyway, if I route the cable over the corner of the roof instead of down 
then around the corner it'll be more than long enough as I intend to 
mount the fed end of the antenna about 5 feet above the roof in a sloper 
configuration, keeping the ground lead as short as practical.

Yesterday after cutting about two inches from each end to make sure I 
had "fresh" braid to solder to, I put connectors on it.  I had  
forgotten just how tough that outer insulation is on the 213.  I nearly 
worked up a blister screwing the PL-259s over it. . .
