Cheapest way to make a new waveguide monopole
Admin
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…
ezRA (Easy Radio Astronomy): How to change Azimuth in a group of ezCol files after these were recorded using a parameter in ezCon 25/5/2025
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…
First LRO PicoMuon detector weekly variation results 25 May 2025
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).

Ideal thickness for copper feed for cantenna at 1420 Mhz
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…
Components I have made for Mini-Antenna Testing Range for EUCARA conference September 2025
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…

Making a 2nd cantenna for the antenna testing range in the NanoVNA workshop at EUCARA 2025
In September 2025, EUCARA is being held at Harwell Campus in UK. I am giving a talk and also running an introductory workshop on using NanoVNAs to test antennae/aerials. As…
Linux Ubuntu for Radio Astronomy: Michiel Klaassen’s UKRAA CosmicWatch Muon Detector Data Analysis Python Script 16 May 2025
Michiel kindly wrote this script for me to help me analyse the data I have from my Muon Detectors – these are the Cosmic Watch Muon Detectors – I have…
