Clamps
A robust range of mounting clamps designed for securing aerials, antenna booms, and pipe supports in a variety of installation environments. The range includes mounting clamps, saddle clamps, universal clamps, and cross clamps to suit different tube sizes, boom configurations, and mounting requirements.
Constructed from cast aluminium with stainless steel or galvanised hardware depending on model, these clamps provide reliable support for antenna installations on flat surfaces, tower legs, vertical pipes, horizontal booms, and rigging structures. Available in multiple sizes for 25mm, 38mm, 48mm, 63mm, and larger pipe diameters, the range offers flexible mounting solutions for both standard and heavy-duty aerial installations.
Mounting Clamp
Models CL-MC25, CL-MC38, CL-MC48 & CL-MC63
This range of clamps uses two cast aluminium saddle blocks held with steel bolts.
They can be used to mount pipe or antenna booms to a flat surface, eg. flat plate, tower legs etc.
Clamps with long bolts are included with aerials, while clamps with short bolts are for clamps purchased by themselves. If ordering without an aerial but require long bolts please let us know or use the L codes when ordering.

Saddle Clamp
Models CL-SA38 & CL-SA48
These clamps are a cast saddle with a U bolt for clamping tubes. Designed to mount aerials to 48mm and 38mm tubing. The saddles are made of cast aluminium with a natural finish. The U bolts are 8mm stainless steel fitted with M8 nuts and spring washers. A 95mm U-bolt is fitted as standard.

Universal Clamp
Model CL-UV
This universal clamp is a heavy duty mounting clamp. It enables aerials to be mounted either in line vertically, or horizontally mounted to vertical or horizontal tubes/pipes. It will also accept the 25mm square booms of our yagis and folded dipoles.

| Internal Horizontal Tube Diameter (mm) | 38 or 49 Minimum 25 Maximum 50 or 25 Square Tube |
| Dimensions (mm) | 90 x 90 x 120 |
| Weight (kg) | 1.2 |
Cross Clamps
Models CL-CRS & CL-CRL
Convenient heavy duty mounting clamps to mount a horizontal aerial boom to a vertical support.
The smaller clamp has been designed with the site installer in mind. The centre section of the clamp is drilled and tapped, which allows one side of the clamp to be assembled onto the boom before fitting the antenna onto the mounting tube.
The larger clamp has been designed following the same philosophy as the smaller cross clamp. With the rugged U Bolts large enough to go around a pipe from 63mm right up to 115mm, it’s a great new clamp solution for larger rigging.
