Hi gang, it's me again, with still more questions:

Looking for (least expensive, if possible) sources of:

* High voltage inductors and caps for the L-Networks at the base of half
wave verticals.

* Six strand 18 guage galvanized guy wire - approx 1200 feet..

* Strain insulators for breaking up the guy wire - approx 120.

* Verification that 11 foot segments are the best length to use when
breaking up wire guys.

On another note, I finally got my own copy of the Communications Quarterly
article nixing quarter wave verticals.  VERY interesting stuff!  However, I
ended up wondering: if avoiding radiation from the radials is the goal, why
wasn't anything said about the radiation introduced by sloping/drooping the
radials.  I thought that also caused the radials to radiate.  I think that
the 1/8 wavelength radials for 7mhz and above elevated verticals could be
brought out perpendicular to the radiator without too much mechanical
difficulty if radiation from them is so important to avoid (the construction
would look similar to a capacity hat, with stiff non-metallic struts going
from the radiator up to the ends of wire radials, or even use aluminum
tubing as the radials and support them from above with kevlar.  Perhaps this
wasn't considered because most of the serious researchers are interested
only in 80 and 160?  But even on those bands compromise 'loaded' radials
could be brought out perpendicular without too much effort (considering how
much effort these guys are willing to go through anyway).

No doubt I'm missing something - but I thought I'd try to find out what.

Thanks, and 73s
