Beams and Nulls (#1407)

Grover, N0GV, asks how a beam will act when placed at different heights on a tower. Does height really matter when placing a beam antenna? What is the optimum height?

MeshCore App Deep Dive – contacts, channels, and more

Think the off-grid mesh world is just for hobbyists? Think again. In this deep dive, we’re breaking down MeshCore—the secure, decentralized LoRa platform designed for professional-grade stability and massive 64-hop range.

MeshCore is rapidly becoming the go-to alternative for those who find traditional mesh networks too "noisy." Unlike other platforms where every device spams the network, MeshCore uses a structured routing system with dedicated repeaters. This means better battery life, predictable delivery, and the ability to scale across entire cities.

How I’m Raising This New 15m Mast

Post author By admin
Post date April 24, 2026

How I’m Raising This New 15m Mast

Today was one of those proper bitty field days – a bit of concrete, a bit of mast mechanics, a bit of rotator tinkering, and a lot of thinking out loud. This is technically Phase 1 of the new 15m / 6m mast project. The job started with pulling out and re-setting the hinge base so it sits straighter in the ground, then checking how practical the whole lifting arrangement is going to be with a three-guy system, a tree pulley, and some temporary side guys to stop any unwanted twisting during lift and lower.

I also dropped the main mast to revisit the magnetic sensor position for the Rotator Genius setup, looked at cable routing and choking, and did a quick real-world test of the winch rope length. That all turned into a useful little experiment in its own right.

There’s also some forward planning in here – Dyneema, splicing, possible temporary baby falling derrick ideas, and how this mast might evolve once the scaffold fittings arrive.

Not a huge “ta-da” reveal in this one – more a genuine workshop day in the field, solving one problem at a time and setting things up for the next stage.

Thanks for following along.

Callum, M0MCX
