Hey, Carl -
"John Smith" wrote in message ... I don't know if I am understanding the instructions correctly. I take them to mean that the 3' 9.5" antenna is attached to the end of the coax and then you come back away from the base of the antenna 12.9" and splice in a 1.9" piece of shorted coax. If this is true, then working backwards from the stub I find that the antenna is about 2.4-j73 Ohms. Seems a bit strange for an end-fed half wave, but never mind that. Oops! I forgot to include the velocity factor of RG58A. Using .73 would make the antenna 23.9-j199 Ohms. But, this estimate is not really useful to you and I probably should have left out that whole paragraph. Just ignore it. John |
