My current HF antenna design source

The EARC 40-6M End-Fed matchbox

This is the design for my current HF antenna...I have been fiddling with antenna and counterpoise lengths and I find the 31 feet with no counterpoise has worked best for me...

Fixed Coax and redid the End-Fed(up)

Well, I fixed the shorted coax connector, and redid the End-Fed antenna...Still fed through the 9:1 UNUN in the posts below, but now has a 31 foot radiator and a 27 foot Counterpoise.  Seems to tune OK??? on all bands 80 through 12 except for 15 meters...I think if I had a roller inductor tuner, that I could tune 80 through 10 more easily.  Come Spring, I am gonna try a different approach and maybe go with Isotrons, or maybe a GAP (no ground plane) antenna.
But for now, I can tune 40 and 20 fairly well, and also 17 and 12 meters. 80 tunes, but very lousy reception, so probably lousy transmit too...10 does not tune well at all.  I can always come up with a 10M dipole or vertical if I want.

P.S. I am calling it the End-Fed(up), because it gives me nothing but trouble most of the time, but when it works, it works VERY well...

Now I need new Coax

Need a straight 50 foot run of good coax...Gonna be another month before I can put up the new antenna properly.

UPDATE:

I scavenged a Coax connector and made up a new length of feedline. Took me 2 times to get the solder job right (first time I had a short).  Now the Doublet just will not tune right, because I cannot get it up high enough...Going back to the End-Fed with the new coax and a counterpoise...Now how long will it take me to get this thing to tune correctly???  I need to find a solution before I pull out all my hair!

New Antenna on the way

Just ordered a new antenna 40-10M from BuxComm...The 4010CD 

Hope that it does the job for me...

73,

UPDATE:  I cannot hang this antenna up high enough right now with the snow on the ground...It will have to wait till Spring when I can take my antenna pole down and get it up to 30 feet or higher...they recommend 32-35 feet...

Tonight I am saddened

Tonight I got word that the pet that was like a child of mine for nearly 8 years passed. "Maggie" May Doodles was the name I called her by. She slept with me every night. We walked the local streets every day. She layed in my lap when I was sad or worried. She never asked me for a thing, but she gave me all her love. You will be missed dearly Maggie...Run wild and free...

2014 CQ WW SSB Contest

Pretty much just fooled around in this contest, but by my log, I have 37 (31 on 20M/6 on 40M) contacts with a multiplier of 47 (38 on 20M/8 on 40M) for 4,512 points...I have had more fun with this than anything I have done so far. Lots of new places contacted...See my log at the bottom of the page.
I put the End-Fed back to 31 feet length, no counterpoise...It seems to tune the best at this length with the 9:1 UNUN. It is now 30 feet in the air from my back balcony to the corner tree. It tunes 40 down to 20M fine, but puts RF in the shack from 17M-6M...I think this is because my coax run is too short, I do not have a proper RF ground, and I am not using a counterpoise. If you stand just 50 yards away, the antenna disappears from site...HI HI  Next year I think I will try Isotron Antennas, unless I find something better for my situation.

Current HF Antenna Doing Well

I am using one of my 9:1 UNUNS with 36 foot of #14 coated wire slung from my back porch up into a tree...The box end is at about 25 feet, and the end of the wire is about 35 feet high...Doing much better this way than as a flat horizontal...hears and gets out much better. I am NOT using a ground or counterpoise...First contact in this configuration was S58N from Slovenia in ONE call....
