CaHRTenna Poseidon Vertical Antenna

The CaHRtenna Poseidon is a portable vertical, designed for portable use from 40m - 6m with the use of a tuner. We suggest the use of a CMC choke at the antenna feed point.

It’s designed as a lightweight, rugged kit that any ham will be able to assemble. You will only need basic tools that you probably already have in your shack. The antenna has been tested at 50w digital and 100w SSB.

The recommended configuration for this antenna is a vertical 25’ element with four 17’ radials spread out in equal directions. The kit is a development platform and we do encourage folks to try different configurations to meet their specific needs.
