Optional: 4 element quad kit for the 50Mhz band
On the same quad boom, a 3-element quad kit for 50 Mhz can be applied.
The electrical characteristics can be found on the dedicated kit page: 4 StQ 50 Kit
By adding the kit to this model, you will have a six-band full-size quad
but with a single boom!

Optional: Element guy wire kit
When ordering the quad or even at a later time
after installation, it is possible to add the "Element guy wire kit"
after installation, it is possible to add the "Element guy wire kit"
This optional consists of the following parts:
- boom extension through a 25 mm diameter fiberglass pole
- 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.
With the installation of this kit, movements of the fiberglass poles
during strong winds or snowfalls that weigh down the braid
of the loops are avoided. The result is a structure that maintains a correct level of
flexibility to dampen the wind's thrust on the antenna, but never reaches
