>> I'm sure it will play well in terms of keeping your transmitter happy but the relatively large bandwidth you are measuring is indicative of substantial loss in the system somewhere. This would be a large bandwidth even if you did not have the bandwidth narrowing effects of a shunt feed. << Hi guys, the 3 wires is actually a transmission line and the antenna is well known as Folded Unipole with 200 ohms impedance. My antenna is a Folded Unipole as well and has the same broadband SWR measurement's. The loss is the same for any tuning circuit it has nothing to do with the bandwidth. The ground plane does, and in this case it is the same, right? 73's JC N4IS _________________ Topband Reflector Archives - http://www.contesting.com/_topband |
