Hi Phil
The bandwidth on 160 was so narrow it was basically only good on one single frequency for me. Which was OK, I set it for a specific frequency I used twice a week. All of my other 160 work was done on that Linear Loaded Inverted Vee that I put up. I had pigtails on it and set each leg at a different frequency and it still worked OK for me. As far as the HF9V I was and am still very impressed with how well this antenna has worked for me. Especially in the confines of my suburban yard with antenna restrictions up the wazoo. But FINALLY I moved to a new state, I live in a valley between the Cumberland Plateau and the Smoky Mountains, due to the hill behind my house, sunup isn't until around 9AM. But it is a very high hill and THAT is where I plan on building my antenna farm. I've made many calculations and studied the lay of the land several times, it looks like the ideal spot for this area. My only concern will be the coax loss in running over 600 feet of coax up the side of the hill. I would need 9913 for the upper bands. I'm also looking into the possibly of using perhaps a 6 inch wide ladder line. But I'm not savvy enough to know if I can run coax out of the shack to ladder line for 500 feet then back to coax to feed the antenna towers. This is something I will have to study up on again before attempting it. I may try a trick a neighbor about a mile away has done. We have extremely tall poplar trees here. He cleaned the branches and topped one of these poplars and then installed a 25 foot tall mast at the top of one of them for his VHF/UHF antennas. He said it's been up there for over 5 years and the new branches that sprouted have not come close to the antenna yet. So that might be one alternative for me to try also. The HF9V will be ground mounted at the dividing line between my front lot and my back lot, which is only partially up the back hill in a flat clearing where I have plenty of room to run my overkill radials. At my last home in St. Louis, I had over 3,500 feet of radials, some extending through neighbors yards until they reached the streets on the other side of their houses. And, where backyards meet, many had those stockade fences and they allowed me to run dipoles across their backyards about 10 feet above the fence lines by installing 25 foot poles affixed to the fence posts. POed the telephone and cable TV people who had to watch for my lines when working on the utility pole mounted services within their easements. I was not within their easement so they couldn't just knock them down and leave them laying on the ground, hi hi..... It was so long ago, I don't remember which bands these apply to, but those horizontal metal strips on the antenna. On the upper one (after installing the 160 coil) I took a pair of alligator clips and a piece of wire about 4 inches long (2 inches each side) and experimented by making this top bar a little wider. I do remember it worked for whatever reason I was doing it. So I drilled two small holes in each end and laced a new copper wire through this allowing about 1-3/4 inch extending beyond the natural length of this horizontal antenna member. But I believe this may have been to use an out of ham band frequency for our emergency communications. The antenna was up for several years, so you tend to forget things you had to do when it was initially installed. I never had problems with it, so I never messed with it. It seems there are some photos on my web page somewhere, but I don't know if they include the HF9V or not. The URL is http://archimedes.galilei.com/raiar if you want to have a look around and see. I'm quite lax on updating my web page, and it seems I never remove anything, just add from time to time. So there's no telling what you may find there. TTUL - 73+ de Gary - KGØZP |
