swr goes up on antenna
"Channel Jumper" wrote in message ... Sorry Jeff, but you just shot yourself in the foot! If you transmit a dead carrier and you don't say anything you are in fact violating the Part 97! All you people did was reaffirm what I had already said. The sad fact is that we give out licenses like lolly pops at a barber shop with no real instruction involved and once a person gets a license they automatically think that they don't need to know the rules or anything that they learned to pass the exam to get the license. Had we had real Elmer's when we gave out those licenses, we wouldn't have 90% of the garbage we hear today on the HF radio! As far as amplifiers goes, yes I can see someone using a amplifier on 160 meters in the summertime, but the rest of the time, all they are doing is broadcasting - not really serving any purpose. If the OP bought a commercial OCFD in the first place - he wouldn't have these problems. The people that made comments about their OCFD out performing a center cut dipole for X frequency doesn't understand how a OCFD works. If you have a 80m OCFD and you use it on 10 meters, it acts like a 8 wavelength long 10m dipole. You actually get a realization of GAIN from the OCFD when you use it on 40 or 20 or 10m... Unfortunately in my book to realize gain you must give up something in one direction to improve your signal in another. So the term GAIN really isn't relevant here. Instead of using the term GAIN I should say improvement, because improvement would be a more relative term. Yes, I got my ham license out of the same Cracker Jack box that I got my First Class Phone license out of around 1972. The OCF I have is home built, but the blaun was bought. It does not take too much to add about 40 feet of wire to one side and 80 feet to the other side. The testing I did was on 80 meters around 2 or 3 in the afteroon. The band was almost dead, Not a signal within 50 khz of either side of where I was testing. I did ID and ask if the frequency was in useseveral times during the test. Ham radio is partly for testing and experminenting. That is what I was doing for about the 10 minuits total. You can look in the books and theory and everything else, but unless you put up several antennas and compair them in the same area like I have , it is all just a guess. The ground, trees,and atmosphere are almost impossiable to modle on a computer for every location. The OCF I was compairing was to an 80 meter dipole on 80 meters only, not other bands. Without being able to rotate an anenna, you have to take what you get as far as where the main lobe of the signal goes. Most of the ones that complain about amplifiers not being needed are the ones that don't have one,but wish they did. I seldom run one,but at times it does make a big differance in making good contacts and not. Same as with a beam. People with poor antennas say they can work all they can hear,but they do not realise they are not hearing much either. I don't knock people with poor antennas. At one time I did not have a very good antenna system either. Lived on a small lot without any trees and the best I could do was a dipole up about 20 feet. Still had fun with what I had. The name is real and the call is KU4PT, unlike some that post on here witout a real name or showing a call. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com |
