Two clamps are available, one for standard booms (the vast majority of aerials in this country) with 15mm cross section, and one for larger 20mm booms. Both clamps can tilt the aerial up to 60 degrees, not that you should normally ever need to incline an aerial that far…..
Zinc plated steel and Heavy Duty wing nuts (the latter are also available separately).
Please note: The purchase of a separate clamp is not required for any of our aerials, because they’re all supplied with one !
P&P is cheaper for this item if you phone the order through !
