N8KDV,
Other then the fact that these two Antennas are basically
a "Low Noise Design" (LND) Random Wire Antenna:
GoTo= http://www.iserv.net/~n8kdv/pics.htm
* Wire Antenna Element (AE)
* Matching Transformer (MT)
* Grounding Point 'located' at the AE & MT Junction
* Coax Cable Lead-in-Line
QUESTION #1: How would you further Sub-Catagorize your Antennas ?
Seventy Foot LND Antenna:
[ ] Just-a-Basic 70 Ft. Low Noise Design Random Wire Antenna
[ ] Ground Effect {NVIS} 70 Ft. and Low Noise Design Random Wire Antenna
[ ] 20 Meter Band and above Long Wire Antenna that incorporates
the Low Noise Design Antenna Concepts of John Doty

Went back and re-read this and figured I had a question. What makes you think
this is a 20 meter and above antenna? Also, I'm afraid to point out that the
design pre-dates the John Doty concept. (as far as I know).

Two Hundred Foot LND Antenna:
[ ] Just-a-Basic 200 Ft. Low Noise Design Random Wire Antenna
[ ] Ground Effect {NVIS} 200 Ft. and Low Noise Design Random Wire Antenna
[ ] 60 Meter Band and above Long Wire Antenna that incorporates
the Low Noise Design Antenna Concepts of John Doty

Works good below 60 meters too, also on MW, as does the 70', see also my
design concept note above.
I thank John Bryant and Nick Hall-Patch for publishing the matching
transformer concept, and the general antenna design in the 1988 issue of
Proceedings, put out by the Fine Tuning radio group.

QUESTION #2: Do you still 'offer' For Sale your
"N8KDV" Ten-to-One (10:1) Matching Transformer ?

Hi Steve. How did you come up with that ant. on your website.
It seems to work good.

Nothing much to the antennas, they are simply 70' and a 200'
wires mounted about 9' above the ground.
I use matching transformers into coax, and the coax is buried,
then heading into the house.
The shot is from the end of the 100' wire, before I lengthened
it to 200'.
They seem to work OK, and this is the type of antenna I've been
using since about 1988 or so.
I plan on putting up a inverted vee for at least the 60 meter
band this coming summer.
