The waveguide in the centre of antennae sich as cantennae are made of a copper quarter wave monopole. The cheapest way to obtain a stiff enough short piece of copper…
The following parameters allow ezCon to override the azimuth or elevation embedded within the data files from ezCol and use the parameter added to the ezCon command line instead: -ezConAzimuth…
This graph compares last week’s results with those found at a professional observatory in Finland (latter is neutron flux but gives basis for comparison as muons and neutrons go hand-in-hand).

The ideal thickness (gauge) of copper wire for the feed in a cantenna (typically for Wi-Fi at 2.4 GHz) depends on both practical and theoretical factors, mainly skin depth, mechanical…
I am running a NanoVNA workshop at EUCARA 2025 at Harwell Campus and as part of this I am going to demonstrate a mini-antenna testing range = I have been…
