Windom antenna
I am thinking of putting up a windom antenna (see
http://www.hfantennas.com/Products.htm )and would like comments from anyone who is using or has used one about the performance. Primay band of interest will be 40 meters. Thanks |
I have a friend down in Missouri that just put one up. He's having
excellent results with it from what i gather. Winston are you around somewhere ? Robert VE3 something or other. "JJ" wrote in message ...

The Portsmouth, VA ARC (W4POX) uses them during Field Day on 40 & 80 M,
we've had outstanding results. Joe N2LJD "JJ" wrote in message ... I am thinking of putting up a windom antenna (see http://www.hfantennas.com/Products.htm )and would like comments from anyone who is using or has used one about the performance. Primay band of interest will be 40 meters. Thanks |
'JJ',
'Windom' antennas work well if they are used/erected properly. They aren't really any 'better' than any other antenna used properly. The 'all band with no tuning' is more 'sales hype' than fact. But, they do work. I think the particular antenna you are looking at is more accurately called an 'Off Center fed' than a 'Windom', but that's sort of 'picky'... 'Doc PS - I also think the price is sort of 'steep', for a basically simple antenna. |
I believe that today's "Windoms" are not true Windoms!!
Ah Ha! Blasphemy surfaces. As soon as "Ice Out" and the end of "Mud" season occurs I will be installing a 1930s version of the "Windom". Used one from Massachusetts with results equal to a dipole but simpler construction.

I need something simple for the moment that I can quickly put up and work several bands. I think this one is what is/was referred to as the "Carolina Windom"? Thanks to everyone for the replys, I think I will try it. |

Well I much prefer my old inverted vees but it does get me on the air on multiple bands with one feed. I am sure that the marginal height of my system is a negative (about 25-30 feet or so). Again it does get me on the air and the K-2 tuner handles things well enough although the thing is supposed to function well without a tuner.

Hello,
I use a home made (low $$$) OCFD type antenna for 80-10m + WARC of the Fritzel FD4 2kW version's length; fed with 300 Ohms twin lead and a 1/6 current balun out of the shack. It needs only minimal AT tuning for 20m and the WARC bands, 15m is no problem due to a second shorter OCFD cut for 21 MHz at a common feed point. For 160-10m operation a 2X20m Levy antenna with Levy tuner and 15-20m 300ohms twin lead would be a better choice. 73 de F8BOE Olivier ...-.- "JJ" a écrit dans le message de ...

I'm not a technical expert like many on this group, but I have used a
Antennas & More TNT-Windom (OCF dipole) for a few years now both in an inverted-vee dipole and "windom half-square" configuration up 35' (33V'-66H'-33V') set up N-S. This TNT model has a choke balun near the feedpoint that helps with RF on the coax. The best set-up was the half-square which had low angle broadside gain E-W on 40M and on some higher bands. Good 80M coverage given the height too and excellent DX above 40M. Good matches everywhere (17M & 12M too, more difficult on 30M, 15M and 10M) but my built-in tuner on the TS450SAT did it all regardless. I even used an external tuner for 160M tuning - poor performance, but okay for 400 miles around - for extra multis in contests. I think this model is better than the Carolina Windom because the Carolina vertical element needs to be 15' from any metal - according to a phone call to the manufacturer. I hang from a TV tower now so the tower proximity would interact much more the Carolina model. This was my 2nd commercial purchase to replace a hurting G5RV and I feel it works MUCH better than the G5RV it replaced. I still use it for 80M-40M portable contest work. ...... va3kai "JJ" wrote in message ...

This only confirms that both of us have been in ham radio too long!!! My first Novice 80 CW antenna was a true Windom. W1GID, Ralph Tedford, one of my early Elmers, installed it for me. I ran an ARC 5 transmitter into it. Funny thing though, I kept getting tingling sensations off the key until I lengthened the feed line about 25 feet :-) I earned my first award with that radio and antenna: "WATV" Deacon Dave, W1MCE for 50 years |

Primay band of interest will be 40 meters. Thanks I use a homebrewed Windom antenna as my sole HF antenna. Works VERY well on 80, 40, 30, 20, 15 and 10 meters. Tunes easily with an MFJ-941D tuner, and performs very well in all directions. It's a little twitchy on 12 and 17 meters, but by reducing output power on the transmitter, it's useable...

Primay band of interest will be 40 meters. Thanks I have operated on both an 80 meter G5RV and an 80 meter Carolina Windom. Both performed well, but I lean towards the Carolina Windom. The SWR on the Windom is below 3:1 on all bands and my internal tuner has yet to have a problem matching it to any frequency. I resolved the problem of the vertical arm by supporting at the feed point with a fiberglass mast at 40 feet. Hi, Robert Win/W0lz |

Shorten the series section transformer length on the G5RV to 22 feet and you will have no trouble tuning it to a match on 75m. -- 73, Cecil, W5DXP -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Tie the long side of the second Windom to the short side of the first one, and vice versa. Feed the thing with a balanced line, or with coax through a balun. I don't have EZNEC (it won't run on Macs) so I don't know what the pattern would be like, but if everything was symmetrical the feedline ought not radiate.

David, ex W8EZE -- David Ryeburn To send e-mail, use "ca" instead of "caz". I modeled the above with EZNEC using two perpendicular one-half wave elements one-quarter wave above ground at 7.2 Mhz. Each half-wave was divided at a point one-sixth wave from the end The short end on each side of the feedpoint was connected to the long end of the perpendicular wire. The source was placed on a 2 inch wire between the two short-long pairs. I included a wire to ground from one side of the feed point to show shield current. At 7.2 Mhz, the feedpoint impedance was 59 - j157. I didn't attempt any element adjustments to make it resonant. The far-field pattern approaches omni-directional with 7.7 dbi at an elevation of 60 deg. The wire from feedpoint to ground shows very little current. At 14.3 Mhz, the feedpoint impedance is 37 + j138. The far-field pattern is bi-directional with 11 dbi at an elevaton of 30 deg. The wire from feedpoint to ground shows current similar to the element current. So it appears to me that the feedline may not radiate on some frequency but definitely will radiate on others.
