Fan dipoles are fun – but this is a compact version using a linear loaded style 80m dipole and 40m legs too. Performs fine but the tuning was a nightmare! LOL Have fun, take some inspiration and try it yourself! Callum. M0MCX. DX Commander.
We probably only have 40m right now due to taking the Signature 12.4 down before I was ill. But we do have a low-to-ground dipole up, good for UK and some EU I think. See you in the morning. Callum.
Facinating results today when I raised the antenna 1m (40 inches) at a time. No frills. Just hard fact science. Follow me for the results! Callum, M0MCX. DX Commander

I discovered this trick this week when I ran out of plastic carabiner clips in the field.. I tied a double overhand knot instead and connected the shock cord to it. Hell, it worked GREAT! I now prefer this method. See what you think.. Callum M0MCX. DX Commander.
Hi friends.. I *MIGHT* be restricted 100% to 80m on Friday because I might take down the Signature early tomorrow morning for some R&D.. I have a rather amazing idea that will please you.. If I do, I’ll be on the VERY low dipole at about 8 feet above ground. See you then. Callum.
Cruising HF looking for contacts – let me know if you can hear me and we can have contact. Join in, listen in – or chat. All for fun. Callum, M0MCX. DX Commander.
Bizarre results on the upper end of HF noticed for this hf vertical antenna. We think it’s effectively a grounded capacitor issue forcing very low SWR on 12, 11 and 10m which is also reducing radiation efficiency. See what you think. Callum, M0MCX, DX Commander.
Antenna Modelling (Modeling USA): In this video, we walk through the history of antennas before moving into a beginners guide to making your first antenna model with MMANA. Recorded Live to Gold Coast Amateur Radio Association. Sit back and join us. Link to MMANA below this. Callum, M0MCX.

Dipole legs are normally just under 25% for each dipole leg (depends on height above ground) but you can shorten this to between 16-18% by loading it up in a linear fashion. Tom (M0RMY) and I made one. Let’s show you how we got on. Callum, M0MCX. DX Commander
