Secure two masts together with this heavy-duty V-jaw clamp built for outdoor antenna work. The forged V-block bites evenly around round tubing while the twin M6 U-bolts deliver a stable, slip-free hold. All hardware is 304 stainless steel for excellent anti-rust performance in rain, sun, and salt-air environments—perfect for rooftops, towers, boats, and remote installs.
Use it to join a vertical support mast to a smaller antenna mast, stabilize rotator standoffs, or add accessories such as stay bars and cross-members. The 20–55 mm adjustment range covers common TV, CB, and ham-radio mast sizes. Installation is straightforward: position, align, and tighten.
Package includes: 1 × V-jaw mast clamp bracket with dual M6 U-bolts and hex nuts.

Frequently Asked Questions
Quick answers about over-the-air TV antennas and how they work.
An OTA antenna allows you to receive free local TV channels broadcast over the air by nearby stations. It connects directly to your TV and picks up signals without the need for cable or satellite subscriptions.
No. OTA antennas work independently of the internet. You only need an internet connection if you use streaming apps on your TV.
Available channels depend on your location, distance from broadcast towers, terrain, and antenna placement. Most users receive major local networks such as ABC, CBS, NBC, FOX, PBS, and other local stations.
The antenna is compatible with most modern TVs that have a built-in digital tuner (ATSC). Almost all HDTVs sold in recent years include one.
Yes. An OTA antenna delivers whatever signal the station broadcasts, which can include 720p, 1080p, and in some areas 4K (ATSC 3.0), depending on local availability.
For optimal reception, place the antenna as high as possible and near a window or outdoors when applicable. Avoid obstructions like thick walls, metal structures, or large electronic devices.
Some models support dual outputs or can be split to multiple TVs. Signal strength may change depending on the splitter, cable quality, and total cable length.
