Today we’re lowering the 40ft / 12m mast again so I can finally finish things off properly – fit the Rotator Genius magnetic sensor, run the coax, tidy up the guys, sort the handover system and generally make the whole thing operational.
This mast is basically a smaller version of the big 19m / 62ft mast further down the field and uses the same idea:
– falling derrick
– pulley system
– ropes and orphan guys
– 12V winch
– and a fair amount of trial and error
Real-world engineering, knots, shackles, lowering and raising the mast, routing coax and solving problems as they appear.
We also:
– test the Rotator Genius magnetic sensor
– discuss guy geometry and rope stretch
– cut the coax slot into the mast
– run Messi & Paoloni coax
– talk about the future 15m Yagi
and listen to some very noisy sheep at Holly Farm.
Honestly, this was just a lovely day in the field.
