 I use a short,2-3',length of RG-58-u to get a bit of capacitance into the 
feedline which is usually RG8-U for HF.
 The different velocity factor and capacitance of the RG-58 seems to help out
in broadbanding an HF antenna. I used this method to get a 2MHz. bandwidth 
out of an RM-11S 11m load a long time ago. The thing was 1.5 to 1 from 
26.000,flat
from 26.500 up to 27.800 and climbed to 1.5 again at 28.450Mhz.
 The RM-11S was mounted on the trunk-lid of my Malibu and the shaft was the 
old
fold-in-the-middle 54" one. Got out like stink and talked distances most 
sing
a K-40 couldn't even dream of.
 I'm anxious to see if this will work on 80 and 160 when I get it going.
 JE> Sounds good.  Remember the added capacitance for easier loading at lower
 JE> frequencies.  Even Hustler antenna needed 'em.
 Will try it out if I can get the rig I want.

 Nope. Restricted to 80 and 160m until I get 12wpm cw.
 Want to try 80m or 160?
 Weekends seem to be my only `free' time right now.

 If the chooke was soldered across a resistor (Heathkit did this alot) the
rating of the resistor may have been low enough to heat the choke and fry it.

 Good job.

 Because they -have- the KW.
 Those that have the juice insist on running it full-time when 20w or less 
will
do to get you thru.
 I laughed at the guy who broke a QSO up on 80m with several US and Canadian 
hams round-tabling with a guy in the Samoan Islands.
 He wanted Samoa so bad he was cranking up into splatter and overdrive on his
amp and getting people 20Khz. either side of him ticked off.
 The laugh is I worked the Samoan station with 50w.
