Optional: 3-element quad kit for the 50Mhz band
The 3-element quad kit for 50 MHz can be applied to the same boom as the quad.

Adding the kit to this model will give you a six-band full-size quad
but with only one boom!

Optional: Element guying kit
When ordering the quad or even at a later time
after installation, it is possible to add the "Element Guying Kit".
after installation, it is possible to add the "Element Guying Kit".
This optional extra consists of the following components:
- boom extension through a 25 mm diameter fiberglass rod
- 3mm Mastrant guy wire, which connects the elements to each other and then connects them
to the boom extensions
to the boom extensions
- loop made of 3mm Mastrant, to be applied to all elements.
The installation of this kit prevents the movement of the fiberglass rods
during strong winds or snowfalls that weigh down the braid
of the loops. The result is a structure that maintains a correct level of
flexibility to dampen the wind pressure on the antenna, but never

flexibility to dampen the wind pressure on the antenna, but never
exceeds the critical level of mechanical stress.
