There are always new links popping up and I try to keep up with them too! As soon as the neighbors find out that you're a ham radio operator, several things will happen. 1. You will immediatly be blamed for all manner of electronic failures. Kitchen appliances, computer crashes, and prematurely dead batteries will all become your fault. 2. Neighbors will assume that you fix things for free. Training the neighbors to pay for your time will be a challenge. 3. The phone will ring at 2AM asking if you're on the air and causing reception problems with OTA TV, cable TV, satellite TV, etc. After mucho years on the air in mucho locations I can say I've been there, done that! This is however, my first real experience using a very limited antenna and QRP. My theory is that if it doesn't work on paper, it's not going to work when you build it. There are plenty of "standard" antennas that usually work the first time (if you follow instructions). However, you seem to be interested in designing your own. Therefore, I suggest you download the demo version of EZNEC, or the free 4NEC2, and proceed to model your prospective antenna system. When the computah says that you're close, then it's time to build it. An MFJ269 or similar antenna analyzer is handy for verifying your calculations. I have an MFJ-259B -- couldn't live without it, and with all the stuff I gave away this was the one thing that I just couldn't part with. Hint: One of my ham friends moved into a CC&R (covenants, conditions and restrictions) infested condo farm. No antennas of any kind. The condo council had at least one member that was certain that property values would decline if a ham was allowed to operate from the condo farm. So, I leaned a 20ft aluminum extension ladder against the house and ran a wire to the radio. It worke quite well with a tuner. The ladder was left leaning against the condo for a bit less than a year before the condo council discovered the ruse. There was a short debate. The council decided that since it had been in operation for a year without any complaints or detrimental effects, it could stay. Good move! I've always maintained that if you give me any old piece of metal almost anywhere, I'd find a way to load it and get on the air! And I've done it time and time again. I did 26 years in the navy and moved around a lot -- quick and simple antennas were a must! I also helped a lot of chums who moved into condos or rest homes get on the air using similar methods. This case now though, is the first time I ever went into a place that seemed impervious to signals. I've often operated from indoors with no problem, and here, the first time I flashed up the receiver, thought it had gone dead -- that's how bad it was. The first thing I did was checked the protective diodes on the antenna connector and as soon as I found them OK, opened the window and strung a short wire outside -- then everything was 5/9 plus! As per another sailor many years ago said, 'I have not yet begun to fight!' Irv VE6BP |
