THE EH-ANTENNA (80m Version)
A test of an 80m EH-ANTENNA
This was conducted similar to the 40m EH-ANTENNA test.
I suggest you read the 40m test first to understand the test setup, then return here to read about the 80m test results.
All antennas used in the 80m test were identical to those used in the 40m test, except of course the 40m EH-ANT was replaced by the 80m EH-ANT. It was mounted on the same mast in 9m height, using the same coax feedline, with an RF-Choke before entering the house.
The results are spread across a few different documents, and I will need some time to copy them into a single PDF.
The 80m EH-ANTENNA is about 6 ft. tall and shown on the right.
If you mount it close to the ground, it will not work.
NO MATCHBOX WAS REQUIRED. I RAN 750W (Legal Limit in DL).
Here is a sample of some of the QSOs I worked using the EH-ANT on 80m:
As you can see in the "snip" above, several 80m transatlantic QSOs were made using the EH-ANTENNA and I usually connected on the first call. As you see, in a period of 30 minutes I worked 7 stateside hams (from Munich) with this tiny antenna.
I have 4 more logbook pages showing lots more results.
Since it was during a contest, the exchange was always 599.
In the columns in the middle, I took the time to record the actual S-meter reading of the 3 different test antennas.
Again, it is wrong to believe the 80m EH-ANTENNA is an Ass-Kicker, because it is not. But it does enable you to make transatlantic QSOs on 80m on an antenna with a tiny footprint, running legal power.
Just because you have a very tiny back yard and cannot erect long wires or a tall vertical, that does not mean you cannot work DX on 80m.
My 80m EH-ANTENNA was mounted with its base at 30 ft., on a pole located about 10 ft. away from my house.
The coax run to the house was about 30 ft., with most of that laying on an aluminum garage roof.
I inserted an RF-Choke just before the coax entered the house.
The 80m EH-ANTENNA is built inside a thick PVC pipe, about 6 ft. long.
If the neighbors ask, just tell them it is for monitoring the weather!
This is a "trick antenna" or call it a "gymmick antenna", whatever.
But contrary to what many experts believe, this trick works.
I AM NOT PROMOTING THE EH-ANTENNA - NOT AT ALL.
I'm just saying if it's the best you can do, go for it.
Get on 80 and have a ball.
AN ABSOLUTE TRUTH:
It is impossible to work transatlantic QSOs on 80m
with an antenna "which can't work".
BTW, here's a close up of the installation of the EH-ANTENNA.
That huge cable tied to the drain pipe is actually the coax. It just appears bigger in the picture!
I took the picture while leaning out the window.
And this picture shows the three antennas used in the tests:
As you see, a full size 80m dipole sure takes up a lot of room.
The Vertical Dipole and the EH-ANTENNA only require about 1 sq. ft. of landscape!
As you also see, you can transplant an OKIE to Bavaria, but he will still drive a pickup truck!
IF YOU HAVE ANY YARD AT ALL,
DON'T LET ANYONE TELL YOU THAT YOU CAN'T GET ON 80M!
