Am looking for anyone running this antenna or any Carolina Windom
I want to go out and get the Windom 80 but i see no were on there web site that says the SWR ratio. I run a Auto tuner that you find in most newer rigs. Most of the tuners can only tune 3.1 or lower SWR. So my question is to you that might have used a Windom. How are they on Match to a Auto Tuner. I also have a Comet - Maldol Covers 8 bands HVU-8 3.5 / 7 / 14 / 21 / 28 / 52 / 144 / 446 / All with in a 9 ft antenna . For Sale $150 plus shipping. New it cost $299 You can mount it on a deck and put the radials on one side of the antenna Makes for a good condo antenna Or mount it on a 10ft pole in the yard. Works fine. The antenna is only about a month old. TNX for any input. 73 Steve |

They also push the mjf-914 auto tuner range extender, and indication an auto tuner by itself might not be enough for all bands. bob k5qwg |

Steve:
I have the Carolina Windom 160 with the short end up at 40' and the long end up at 10' from the ground. The vertical matching section (the vertical part with the isolator at the bottom) hangs with the isolator about 5 feet from the ground. I would imagine this is the minimum installation height that works decently with this antenna. It does get heard, and I can hear on all bands from 160 to 10m, however, my Icom AT-500 automatic tuner won't tune it on 20 meters and I need to use an external/additional manual tuner to cover 20m. Looking at the antenna with an antenna analyzer, I find that most of the real dips don't really correspond to the ham bands in my installation. I assume it would be somewhat different if I bothered to try to tune the antenna or if I got it up higher. Alas, I am getting ready to move, so am not putting any additional effort into antennas for this QTH at this point... SWR is all over the map. On some bands, it's almost reasonable, on others way over 10:1... Most of them must be somewhat reasonable, though, or my AT-500 wouldn't auto tune them with decent results. I can say that it does seem to act somewhat like a top loaded vertical on some bands (I've heard that the vertical matching section is a heavy radiator on this antenna), and seems to have a bit of directionality (off the sides) on others. Perhaps when I get to the new QTH I'll be able to support it higher at both ends and give it a real test... I can tell you that it is definitely better on 40m than tuning my multiband beam (20-10m) for 40m, even at short range... The db ratings on their web site are either fiction or a wish. They indicate "up to 10db", but I couldn't tell you where that might be, or how you'd have to mount it. Perhaps if you got it up with both ends over a hundred feet high, it would seem like it had 10db of gain at some frequency, but I can't imagine where or why. As an off center fed, horizontal dipole it seems to work OK, but you have to take the DB ratings with a grain of salt (and the best thing to do with the salt is put it on the rim of your Margarita).

Have used the CW80 and CW40Plus both required a good manual antenna tuner to
work all bands covered. Both are excellent antennas. Good Luck! Larry/W4LM "Steve" wrote in message ...
