Yagi Strut Kits |
When planning the installation of a large Yagi antenna, the need for a Strut Kit to support the boom properly is a vital consideration. The main factors to consider when deciding the need for a Strut Kit are : |
• The antenna boom length, weight and wall thickness.
• Wind loading and potential for side-to-side flutter, particularly in coastal and alpine regions.
• The usual weather conditions at the site, especially where there is any likelyhood of snow.
• Bird loading. |
All of the large Yagi Y100, Y200 and Y300 series antennas most definitely require a support strut kit due to their sheer size and weight. The right-angle mast clamp alone will not be sufficient. |
Yagi 15 element models Y415, Y615TV and Y815 at 1.85 metres and longer should also receive consideration as candidates for support struts, particularly the heavier stainless steel models. |
ZCG Scalar construct Yagi Strut Kits 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 in any way. |
A Yagi boom may be supported from above or below, depending upon the mast space available at the site. 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. |
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. |

YS1-100 |
YS1-23 |
YS1-48 |
Single Strut Kit to suit Y100 series Yagi. Support from above.
Includes clamps. |
Single Strut Kit to suit Y200 or Y300 series Yagi. Support from above. Includes clamps. |
Single Strut Kit to suit 15 element
Y415, Y615TV, Y815 series Yagi. Support from above.
Includes clamps. |
|
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 and also add stability against
side-to-side wind flutter.

Custom Design Strut Kits for Yagi Stack Arrays |
|
For Yagi’s mounted in a stack array formation, ZCG Scalar can manufacture custom kits which include joining struts to maintain precise spacing between antennas according to frequency.
Pricing for custom design strut kits will depend upon requirements.
