wrote: Just think of what I could be describing, a 20 metre antenna with a ten to eleven degree TOA, turning radius of a conventional dipole and a feed point of something less than 75 foot high. Now thats good for small real estate and a light duty rotor tho the U.K. authority may baulk at the height. I have built very long boom yagi.s. for 20 M some with a couple of reflectors and some with as many as 13 elements but this direction is limited by minimal advances compared to complexity, thus my statement as to what the hobby needs for it to grow I see what you are asking for. I would definitely want one myself, but the problem I see with your theory is that the antenna can't change the earth's effect on electromagnetic waves. I have never had a beam up 75 feet. I had a TA-33 JR up 35 feet, about half of the height you recommend. I can't say I had the perfect TAO, but compared to the dipole and a vertical I was using before I got it, the beam significantly improved my operating. I was county hunting at the time (operating with mobiles in each US county) and the short beam made the difference between not hearing a car and exchanging 5-9 signal reports. While it wasn't perfect or optimum, it was an improvement. I guess that is the best we can hope for. A better antenna for the same space. I like building mostly wire antennas and I have a few designs in mind and in the works. There are many to choose from to try. Maybe one of them will be an improvement. When it comes to making a contact, I have resigned myself to this one fact: If there is no propagation between two points, there is no communications. If there is enough propagation, even the poorest of stations can communicate. I wish you the best on your DXing and antennas. I've enjoyed the topic. 73 for now. Buck N4PGW -- Buck N4PGW |
