Re: [Elecraft] Antenna Recommendations for the K3 ATU
I am using a TW2010 by TW antennas. It is a five band, 10 thru 20 meter, compact vertical dipole. The antenna easily breaks down and stores in a three foot long travel bag and has many good reviews on eham. I think it is a good match with my K3 because it is very well made and very portable. perfect for some low angle radiation near the sea shore! Bob W9RFS Allen J.

RE: [Elecraft] Antenna Recommendations for the K3 ATU
Jim, K9YC and David, G3UNA, offer excellent suggestions: get up a basic antenna! (I'm an open wire fan myself.) The two biggest mistakes I see among those trying to put up a basic antenna are: 1) Trying to use coaxial line at high SWRs. You can throw away most of your RF easily that way. 2) Using a short (<1/4 wave) antenna with little or no ground. For your reading enjoyment (and antenna edification) I recommend highly these two books: HF Antennas for All Location, Les Moxon, G6XN: An excellent reference with >300 pages of theory and practical ideas for designing and erecting all sorts of antennas. Practical Wire Antennas, John D. Heys, G3BDQ: A slim (<100 page) volume with little theory but a great many practical ideas for stringing up wire antennas that work. Yes, both of these books come from our fellow Hams in the British Isles, but they are both available here in the "colonies" through the ARRL and other sources.

Gawne wrote: >I'm setting up a station after many years absence from Amateur Radio There is NOTHING unique in the K3 with respect to how it works with antennas. It is simply a very excellent radio with a very good antenna tuner. I've been licensed for 53 years, but off and on the air for a decade or so twice during those years. Several years ago, I was in the same position you are. I bought several books on antennas and studied them extensively. I suggest that you do the same. They are the ARRL Antenna Book and "Low Band DXing" by ON4UN. In my experience, classic dipoles and verticals are awfully hard to beat until you go to the trouble of a beam. Nearly all verticals need a radial or counterpoise system of some sort to work well. 73, Jim Brown K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Antenna Recommendations for the K3 ATU
This is what I posted yesterday. You might look back in the Elecraft archives for similar postings from others: I do agree with Simon about verticals , if you are *close* to the wet, they will perform exceedingly well. My antenna is very simple, just wire. It's temporary, but works fine for now. I drilled 2 holes in the bedroom wall and slid 2 lengths of nylon tube therein, they stick out a few inches outside. A piece of 450 ladder line about 3 ft or so goes from the PL in the rig to a connector block on the inside wall and the 2 wires from outside feed thro to that. Height above ground is about 15ft at this point. One wire goes to the bottom of the garden about 3ft up, then thro a rt angle for about 6ft rising to 4ft or so. The other wire bends at about 80deg and drops to 8ft at the garage barge board, then thro rt angle down between the houses to a tree at the front, about 6ft up. Wire is 20swg SnCu used on several projects. BTW no rf or any other kind of earth on rig. Occasionally hear US 80m ssb early morning. No balun; after initial tuning the K3 remembers its settings and changes instantly on band change. I think I asked it to fine tune on a couple of freqs but can't remember which. I'll try this for the cubscouts with longer feeder for JOTA and see how it works inverted V style. David G3UNA Hi I'm setting up a station after many years absence from Amateur Radio and hope you may be able to help. I would appreciate other users experiences of antennas they have connected to the K3 ATU and any opinions on the best antenna to use with the K3. Any guidance would be greatly appreciated.

Re: [Elecraft] Antenna Recommendations for the K3 ATU
Allen, 1) Port Soderick - lovely location, I know it well. I am most envious. 2) I'm only using dipoles which are pretty resonant anyway, anything you can put up there should be fine. The K3's ATU matches very well. http://www.braddan.gov.im/gallery.aspx?GalleryID=2&PictureID=24 Were I at you place (so close to the sea) I would be looking at verticals if you don't have a tower. I'll be over on the Island in October some time, just can't face booking a Fly(may)be ticket at the moment. Simon Brown, GD4ELI / HB9DRV -- From: "Allen J.
