Re: End Fed Wire Experiments

Glen Ellis
 

kk5ib01
Been doing a lot of experimenting and testing end fed wire antennas especially with small 9:1 ununs. I have found that a 56 end fed wire, not up to high, 15

I have been using a Long-Wire, End-Fed, with NO impedance matching balun 
for about four years.   
In my experimentation, the trick is to adjust lengths to be ODD QUARTER-wave-lengths 
for the target band.   Mine are 5.5 and 11.  which are Odd on 40M and 20M. 

This is my experience from my website http://www.geocities.ws/glene77is/

 My LongWire Antenna.  Design Info based on this   W8JI article.  

His information is available on his website,  and is extensive and easy to read.
 
my system is build from his  Long-Wire  "Basic Simple System"   on this page  .
 
and a very informative analysis of counter-poise on this page 

...
and  there is  much, much more. 

Documentation for W8JI Long Wire Antenna  (click for PDF version of this page )
 

My   W8JI LongWire    is 180 to 225 ft long, up at 17 ft, running in the shape of "Z", 

now trimmed back to aprox. 188 ft, 
and connected to the antenna tuner via a Current Balun to keep RF out of the shack. 
52 Ohm coax is 17' long , and wire-nutted directly to the End-Fed Long-Wire. 

 
The very long-wire maintains odd-quarter wave-lengths for target bands so no impedance matching Balun is required.   It has aprox. 5.5 quarter-wavelengths on 40M and aprox. 11.3 quarter-wavelengths on 20M. The Antenna Tuner is a simple HeathKit HFT-9 QRP ( cap-coil-cap double-"L" )which is the Standard Antenna Tuner design used by everybody. 

To adjust for lowest SWR on 40 and 20, 
I roll up the far end of the antenna about 6' at a time, into a simple hand-loop. 
This adjustment gathered fist sized loop  is taped securely 
and hooked on my fence at 5' off ground. 
Then I go into the shack, and vary the antenna-tunner, until lowest SWR. 

Certain antenna lengths give 10Mhz, 14Mhz, 18Mhz, 
while the standard adjusted length gives 3.5Mhz, 7Mhz, 10Mhz, 14Mhz 
at near  1:1 at the Antenna-Tuner.   
80M tunes narrowly.  40M  and  20M tune broadly,  both 1:1 . 

Results:
I run 1 W QRPp/CW into the Long-Wire, 
and have worked all states, and half of Europe, and Hawaii, 
with my HW-8  1977  tranceiver.  
It Seems to be efficient enough for my  ONE WATT  20M  system.   

 

GC_W8JI_Counter-Poise_.gif

The Counterpoise wire runs down from the 17' pole, 
then along the brick side of the house, 
and attaches to the back fence ,  ungrounded.
My counter-poise is about 20' long, and not grounded at the antenna. 
Ideally it would be a few feet of the ground, but mine is 10' up, 20' long. 
 

The Counterpoise is not grounded to the earth 
and only  grounded to the transceiver system.  
Only the Coax Sheild is grounded,  and only  in the shack, at the Antenna-Tuner, 
along with the normal shack equipment grounds, and a very close ground rod. 
This Long-Wire is grounded only at the connection of the coax to the antenna tuner, 
grounded ONLY inside the shack, right at the tuner. 


The Counterpoise is positioned off the feed-end of the "Z" shaped LongWire.
The Long-Wire  zig-zags across the house and back yard. 
 

The  1:1 Current Balun has been placed outside, at 17'  
where the Long-Wire and the counter-poise are attached.  
RF in shack is minimal.

I follow the SKCC on Yahoo as well as 4SQRP. The SKCC powers that be have decided to leave Yahoo. Is 4SQRP considering this as well?

Hi Bart,

  I also figured that being in the middle would be good.. unfortunately... I did NOT account for the Prop Princess either.

And we all know what happens when we don't make allowances and adjustments, compromises or ?? for the women in our lives...   altho.. at this point.. I'm not real sure I am inclined to honor the Prop Princess by callin her a woman... ... ... ..

  Good Luck to all in the Winter Season.. looking forward to it!!

Thanks for being there Bart, always good to hand you a pelt!


Have a great day,

Hi to the Foxii and the ones that give them a cardio work out occasionally,

First of all I want to thank Randy for providing this great information for both Foxii and hunters.

Secondly, earlier this summer hunt season I told my wife that I had an unfair advantage being located here in the middle of the continental U.S.  I found out real quick that the goddess of propagation is a goddess with a sense of humor and can teach us a thing or two when we get to thinking we have things figured out:-)

Also, thanks to all the folks that make these hunts available.

I think this was the very first time that Dale/Lee was a fox that I failed to get a pelt from him, IF I was able to in the hunt.  Rotten end to the Summer Fox hunt:-(

Hopefully, condx will be better on 80/40 for the Winter Hunt——well they couldn’t be worse!!!

Hint:  .. we'll be between the two trees marked 14.050 and 14.070  

that should narrow it down a lot!!

I may miss it this year.  I've been to every single one we've ever had,
so hate to miss it but we've got some important stuff to do around the
house.  If I get time I may come out for a couple hours, but I likely
won't be camping this year.

It will be held at the "Big Brutus" retired coal shovel park located in West Mineral Kansas.
This is just a few miles west and South of Pittsburgh, Kansas.

They have hook ups for Campers and RV's as well as tent sites for rent.

Your guaranteed to have a good time and possibly leave with a belly full of smoked ribs??

If you choose not to camp, Pittsburgh has several choices of motels.
