SWR Measurements on dual band 6 meter 4 meter antenna – 9 element 2 connector:
The measured data on the assembled antenna with HP8753ES calibrated at cables end is presented below.
6 meter SWR is batter than 1.1
4 meter SWR is batter than 1.1
Excellent dual band antenna with two independent connectors for 50 MHz and 70 MHz bands PA5070-9-3-2CB. Picture taken on a cloudy day:
Two separate connectors antenna are excellent choice for transceivers with one connector for 6 meter band and second for 4 meter.
Second option is to use standard HF and 6 meter transceiver and 4 meter transverter.
