Sun Valley Machined — First Production Run
Raise and lower your antenna alone, in minutes.
The Tilt-Up Base is the hinge your Greyline has been waiting for: walk the antenna down for a whip swap, a season check, or a storm night — and walk it back up — one operator, no ladder, no helper, no lift truck.
Why a tilt base? A 24-foot antenna weighs under 30 pounds, but physics does not care — it is the fulcrum, not the weight. Our own FAQ has said it for years: over 24 feet, consider a helper or a tilt-up mechanism. This is that mechanism, engineered in our Idaho shop specifically for the Greyline base tube.
The Design, Plainly
- Two precision sleeves interface with the standard Greyline 2" OD x .125" wall base tube — the tube itself stabilizes the pivot plates
- 1/4" side plates, 3/8" Grade 5 pivot hardware
- All-bolted assembly — no welds, fully serviceable with basic tools
- Adds 17" of height to your installation — a small aperture bonus, on the house
- Cut, drilled, tapped, and turned in our Sun Valley, Idaho shop
The 45-degree stop.
The pivot is cut so the antenna swings down in one direction only and stops dead in the upright position. It cannot tilt over the top and fall the other way. Simple, mechanical, foolproof.
Fits: Greyline DXF and DXV antennas built on the standard 2" OD base tube. Larger-diameter base models: a larger receiver is in development — call before ordering: 435-200-4902.
First production run — built in-house in small batches.
