Machined In-House — First Production Run
All the tilt, no digging.
The Deck & Concrete Mount Tilt Base takes our Tilt-Up Base and bolts it flat to the surface you already have: a concrete footing, a deck, a patio, a rooftop pad. Same one-operator raise-and-lower. Same locked upright stop. No ground sleeve required.
Who this is for: the operator whose best antenna spot is not diggable — rooftop installs, existing slabs, engineered decks, rocky ground, and rentals where a poured sleeve is not an option. The Greyline vertical dipole already works on any surface a flag-rated pole can stand on; this base is how it stands there.
The Design, Plainly
- Welded steel anchor plate with four-bolt hold-down pattern — bolts to concrete or structural deck framing
- Gusseted upright carries the same tilt assembly as our Tilt-Up Base Kit
- 1/4" side plates, 3/8" Grade 5 pivot hardware on the tilt assembly
- Interfaces with the standard Greyline 2" OD x .125" wall base tube
- Adds 17" of height to your installation
- Cut, welded, and finished by hand in the Mountain West
The 45-degree stop.
The antenna swings down one way only and stops dead upright — it cannot tilt over the top. Simple, mechanical, foolproof.
Fits — Greyline Or Not
Every Greyline DXF, DXV, and Skyline built on the standard 2" OD base tube. And because the fitting is plain 2-inch aluminum, it also takes any other maker's vertical, flagpole antenna, or push-up mast with a straight 2.00-inch OD base section. Measure around the base and divide by 3.14; 2.375 is pipe, not tube, and needs an adapter.

Mounting Dimensions — Will It Fit Your Existing Bolts?
- Base plate: 8" x 8", 3/8" steel
- Bolt pattern: 5.5" x 5.5" square, center-to-center
- Anchor holes: four, 3/4" clearance — sized for 5/8" anchor rods
- Height added: 17"
Matching existing bolts? Measure center-to-center both directions. 5.5" x 5.5" on 5/8" rods is a drop-on fit. Different pattern? Call us — custom plates are a conversation, not a problem: 435-200-4902
Anchor hardware note.
Concrete anchors and deck fasteners are surface-specific and not included — call us and we will talk through your exact mounting surface before you order. 435-200-4902
