Testing my CP22E VHF 5/8 lambda collinear antenna on 6m and 10m
CP22E VHF antenna has two 5/8 lambda elements connected by a phasing coil. It works well on local VHF repeaters and simplex. It was also my work horse for LEO satellite operations before I homebrewed my Moxon Yagi. CP22E VHF antenna has an SWR of 1.1 on VHF and 2.25 on UHF. Still it captures downlink from International Space Station on 437.800 MHz very well, possibly the principle of third harmonic resonance. I have been able to work even U/V satellites like AO-91 occasionally with this antenna. AO-91 has uplink on UHF and downlink on VHF. As the 6m season is going strong, I wanted to see if this antenna will work for 6m somehow.
My 40-10m fan dipole is currently having high SWR, possibly due to damage by rain. So I disconnected the RG 213 cable with PL259 connector. The cable is 15m long. The cable coming down from CP22E antenna is 10m long HLF 200. I connected both together on the terrace with an SO239-SO239 barrel connector. CP22E antenna is mounted at a height of about 7m from the ground.
