I Made a Compact Fan Dipole for 80m and 40m

I Made a Compact Fan Dipole for 80m and 40m

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.

Friday Morning 10:45 UTC on 40m ONLY – DX Commander

Friday Morning 10:45 UTC on 40m ONLY - 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.

What ACTUALLY Happens When We Raise VHF antenna up?

What ACTUALLY Happens When We Raise VHF antenna up?

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

Cheap Cool Trick connecting Elements to Paracord and Shock Cord

Cheap Cool Trick connecting Elements to Paracord and Shock Cord

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.

Callum’s Friday Ham Radio Live – 10:45 UTC

Callum's Friday Ham Radio Live - 10:45 UTC

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.

Signature 12.4 Multi-Band Antenna – What is This Problem?

Signature 12.4 Multi-Band Antenna - What is This Problem?

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.

I Made a Short 80m Dipole – Linear Loading

I Made a Short 80m Dipole - Linear Loading

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
