Robert (N7GET) and Rudi (K7RAW) are planning a field test of what Steve (K7EAU) suggested in comparing vertical antennas using different ground plane configurations, all radiators are telescopic whips tuned to resonance (no ATU) on 20 meters:
- Ground-mounted telescopic whip with a bunch of silicone wire ground plane
- Raised ground plane using drooped guy wires from a 6 foot tripod down to just above the ground
- Elevated ground plane of 4 resonant radials atop a 30 foot mast at the base of the whip
We’ll use both RBN and PSK Reporter to check signal reports multiple times to get an average. Time permitting, we might even do a receive sensitivity test too.
If you’d like to come watch or maybe bring a different antenna to test, we’ll have the station all set up with a coax switch to connect to your coax to your antenna.
We’re planning to do this nominally on Thursday Jan 2 at Lone Mountain park, Gazebo #F (atop the western hill). We’ll be set up to operate by 0900. We’ll have the gazebo tented off with a heater against any chilly weather to make it toasty comfy inside, so don’t let wind or rain deter you anymore. Bring your own food and drinks.
If you plan to come, please RSVP Rudi in case we have to punt to Friday due to REALLY nasty weather.
