Yagi Antenna Support Strut Kits
The antenna boom length, weight and wall thickness.- Wind loading and potential for side-to-side flutter of the boom, particularly in coastal and alpine regions.
- The usual weather conditions at the site, especially if snow is likely during the winter months.
- Birds perching on the antenna boom.
All of the large Yagi Y100, Y200 and Y300 series antennas will most definitely require a support strut kit due to their sheer size and weight. The right-angle mast clamp alone will certainly not be sufficient.
Yagi 15 element models Y415, Y615TV, Y815 and Y815-20RL with a boom 1.85 metres and longer should also receive consideration as candidates for support struts, particularly the heavier stainless steel models.
ZCG Scalar's Yagi SUpport Strut Kits are made from fibreglass rod with stainless steel end lugs. Our strut kits will therefore not interfere with either the tuning or radiation pattern of the Yagi.
Kits include all the clamps necessary for mounting the struts to a mast up to 50 mm in diameter. A right-angle clamp to mount the Yagi to the mast is available separately.
Yagi Single Strut Kits
 |
A Single Strut Kit is for situations requiring extra support for the length and weight of a Yagi boom not properly supported by a mounting clamp alone. |
 |
Yagi 2-Way Strut Kits
 |
The 2-Way Strut Kit includes an aluminium boom which mounts to the mast above the Yagi. The two fibreglass struts support the Yagi boom from above. This arrangement provides additional stability against side-to-side wind flutter. |
 |
Compression Strut Kits
Where there is insufficient mast space available above the Yagi, then the alternative is a "Compression Strut Kit" which supports the Yagi antenna boom from underneith.Custom Design Strut Kits for Yagi Stack Arrays
For Yagi’s mounted in a stack array formation, ZCG Scalar can manufacture Custom Design Kits which include joining struts to maintain precise spacing between antennas according to frequency.
Pricing for custom design strut kits will depend upon requirements.
