[600MRG] More antenna anthology

[Dave Riley]

What matching network??

I'm getting to be an old broken record but the best performance on 630m 
here after several years and various tries at antennas is:
Can I have the envelope please??

1. No ground radials,not even a house ground is needed...
2. Cost is cheap-cheap...
3. Must work from 17.2khz up to 80 and 160m ( and very well )...
4. A total of TWO parts

OK, go buy a roll of this:  approx 50 bux for 500 feet... 9 strand 
copper #14...
Never has broken here... The best that I can make it break down is some 
corona @ 20kv...

GREAT HV insulation so you don't need insulators in high pine trees, 
just a compound bow.. This one @ 600' circumference has been up for 6 
years and still works DX every night... KH6 to SV8 Rx/Tx, weather does 
not affect tuning...

A good variable cap. total of around 700pf will do, a vacuum for QRO and 
normal for QRP...great for NDBs and GPS stations

OK, one end of the wire leaves the shack through an insulator, goes 
straight up about 65' then SW about 200+ feet, then drops down to near 
ground and back to shack, voila, a nice loop essentially in free space...
Hung with poly rope with NO insulators...

Next in parallel with the loop feed ( no feed line ) is the variable cap 
tuned to 630m...
A piece of double sided PC board with a clip next to the wire feed is 
placed next to an Amrad like e-probe...
I've been using high voltage J fets from Russia for about 5 bux each and 
they will never burn out here with this power ( about 35 watts )...
If you want to get selectivity place one turn of the loop wire around 
the cold end of a variometer and place the e-probe up at the 'hot' end, 
then tune and enjoy only a few khz. of 630m, the junk signals disappear 
at the same time...

OK so I have lousy rotten ground < .5 millimhos/meter, GREAT for 
loops!!!  Hot dam!!! More lemonade...

Strapping a capacitor decade box across the vacuum cap and the loop 
makes for tuning down to 17.2 khz. and it
ALWAYS hears SAQ Grimeton, Sweden transmissions...
Usually QRK5 with paper and pencil...

I place a W1TAG design ferrite doughnut around the loop wire to monitor 
RF current and to help with tuning...
http://www.w1tag.com/RFA.htm ( great project and re-learn )

The e-probe hears in between CW characters so is QSK 24/7... Full break 
in, no relays, keep it simple...

Directional Arrays ( DA ) on 630?? U betcha... No sense sending RF to 
Capetown, put it in one of the two lobes NE/SW here...
Article coming soon on this one... Didn't think a DA was possible with 
the easy loop and 'other wires' out back tuned for best direction...
It's something like Dallas Lankford's 'noise cancellor' only for transmit...

super duper on 630m offending noise )
