Dan/W4NTI http://www.google.com/search?hl=en&i...F4+wave+dipole Searched the web for 1/4 wave dipole. Results 1 - 10 of about 39,100. Search took 0.17 seconds All are SHF/UHF antennas. Your comments below, relative to HF antennas: OK, I'll give you that, although a blanket statement that there is no such thing as a 1/4 wave antenna is equally incorrect. What would be wrong with requiring them to build a quarter wave dipole that is resonate at a specified frequency as part of the test? That is, if the test were changed to be written and performance based. Then you build me a 1/4 wave HF dipole. Again, there is no such thing. A dipole is 1/2wavelength total length. Center fed with 50 to 75 ohm coaxial cable. Cut to resonance using the formula of 468/Frequency in Megahertz. I.E. 468 divided by 7 = 66.857 feet long. This is the NORMAL meaning of a dipole for the Amateur Radio Service. You can use all the other off the wall terms you choose. Above is correct for ARS and should be on the test. As to making it a performance test. Good idea. I agree and my apologies. |
