Greetings!  Does anyone have any construction plans for a simple 10M vertical antenna (1/4 or 1/2 wave)?   TNX/73 de Chris NV9Z

Hi Chris:

I have a few links for some 10 meter vertical antennas and the like.  These are if you like to homebrew or roll your own and are fun projects and you can find many of them even on the "Ham Links" right here on EHAM.  But here is the But part....If you want something very simple, effective, fast to put up, commercial made, and cheap... then do yourself a favor and call COPPER ELECTRONICS out of Kentucky and buy the A-99 for like 37 bucks.  This is a vertical 3 section antenna that is lightweight, can put togeter in about 5 minutes, can most likely have it tuned and mounted in a half hour or less and work very well from 10 to 20 meters...not bad for 37 bucks!

Ok here are the other sites for a 10 meter vertical antenna and the like....73 and good luck on the project de KB9UMT Don  Peora IL

Hi Don!  Many thanks for the info.  I would prefer to build my own, but low cost is also a consideration.  I'll see what I can come up with.  Very 73 de NV9Z

Chris,
   In the 1997 ARRL Handbook on pages 20.21 to 20.30 there are constuction articles on vertical antennas. I'll bet one of those will work for you. I am not sure of the page numbers in the newer versions since I have mine on CD. Have fun and good luck.

You need wire, an SO239, solder, soldering iron, and epoxy cement.  Quarter wave verticle with 4 quarter wave radials.  Use the epoxy to re-inforce the verticle connection point.  You can support the verticle part with a dowel, or hang it from a tree.  You can make a nice 40 meter verticle that you hang in a tree; and it is hard for anyone to see it in the tree.  Use 468 divided by your frequency for the lengths.

If you can find a 1/4 wave CB ground plane just cut about 8 inches off each element and it'll work just fine.  I've used several of these over the years with excellent results.  Sometimes you can find these new in the package for a few bucks at hamfests.

Chris,

Looks like you have received quite a few responses to your post.  Don, KB9UMT, provides some great web sites for you to check out.

I too have built my own antennas for ten meters. Running 25 watts USB.

1.  Horizontal Dipole in third floor of my house.  This was a test antenna, just to see how it performs.  Consistantly made contacts with the east coast and west.  However, due to orintation, no contacts made south or north of my location.

2.  Sloper Dipole up 40' (Slopes to the south 45 degrees and this is the same dipole used in #1).  Works great!  Consistant coverage into the South Pacific, South America, East Coast and West Coast of North America.  This one is a keeper.

3.  Half-Wave Vertical mounted on the ground.  I made a 1/2 wave dipole, and hung it vertically from a tree branch.  Noisier than #2 and the received signals are not nearly as strong as from #2.  However, I am making contacts with it.  Not real happy with it so I am going to modify it...see #4.

4.  Half-Wave Vertical with counterpoise.  This the antenna found in #3 with 1/4 wave ground wires tied together to form a circular ground plande directly under the antenna.  Under construction.  Go here: http://www.karlquist.com/ground.pdf to read an article about such an antenna.

Good luck, have fun and 73!
