[600MRG] More 630m antenna efficiency...

[Dave Riley]

Hi Hi, qsl all om = :-) = Heck, why not have a net around 10kc. plugged 
in to super rods and qso any one, any time, any qrg??

Mebbe NAA will let us tag on to an unterminated radial in order to 
heat/light shacks...  Watch all the N1BUGs light up...

What do they mean that this has all been done before??  One 630m OM was 
looking for a 30' 630m loop and I'd forgotten that the Isotron had 
already been invented... Missed out on that one to, hi hi but came up 
with 20m 1' loop using 12" heavy copper flashing on desk, qso'd with RA3 
one afternoon... Loops have been getting duped for too long now...

Only thing that buggs me is that albore won't speak to me any more so 
better stay legit and make rasberry ( pi ) sounds attem...

Due to most legitimate things going up hill right now, it's time to 
think and grow DX qsl cards...

Am transitioning shack season now so qru 630...

1) 90.5 foot diameter ? how does one build and install such a structure?
I get it,  J McVey.. but it goes in the right direction, just more 
theory to overcome... Engineering is reverse thinking...
Fessenden didn't see cosines all day, he saw the real picture...

is the plane of the wire H or V to the ground ? Hi Rich, vertical fer 
sure with plenty of help from there on out... It's like parasitic...

Can see isotropic but cain't spell it...

cq 630
