We like this dual set. You don’t need a licence, anyone can use them and it has just about all the basic functionality you need. No knobs, just a few buttons and it’s not expensive. Charges via USB C.

We invite ALL Ham Radio companies to make a Christmas Video! This is our attempt. Please smile and laugh at us! Merry Christmas from Wendy, Loki, Gina and Callum.

This is for 40m RX and TX gain in 4-directions. It’s switchable. Needs a LOT of coax for the phasing lines and the main feed and a 3-wire control line too. In this video, we unpack the box, understand how it works – and sort all the cabling to the field.

I nearly lost the tower today! We upgraded the falling derrick, dropped the tower down, added a T piece for the tower to rest on when down and a few other odds and ends.

Calculating how much rope you need for guying any sort of antenna mast can be a fiddle – so I wrote a spreadsheet to help us. If you find a mistake, let me know!

Not sure how they make these so cheap – but it has FCC certification and seems to work!

I made a 14m / 45-ft ham radio mast from scaffold tubes using a "falling derrick". This is how I did it and these were the top questions that were asked many times:

1. No gloves. Correct, I can always let go rather than get tangled in clothing
2. The slot at the base is fine there is no sideways or twisting pressure here only downward pressure
3. The lines will be changed once I have prototyped this (read description!)
4. G- 450 Rotator has a spec of 200kg downward force. Create RC5-1 is 400kg. We’ll fix the Create
5. Marine hardware and pulleys are better. Yes they are (cost!) but this is a cheap prototype
6. You don’t have help? No – what would the other person do other than get in the way?
7. Edge-trim. Now sourced, thanks.
8. The music is listed below
9. Twisting pulleys will get fix on next upgrade
10. Still worried about the rotator? Don’t be
11. Yes – some day we’ll get a winch. Hang on
12. Detuning the mast from 40m – won’t coax and ethernet cock calculation up? Maybe – but I still need to detune the mast.
13. Yagi is off by 1.8 degrees. Yes – not checked before lift. Fixed next time it’s down
13. Does the PoE Ethernet up the pole generate any noise? No.

Music at end is "Celestial Spheres – Ave Air" [found on Epidemic Sound]
