:Optional: Kit 4 elements quad for 50Mhz band 235,00 € (iva incl.)
On the same boom of this quad, you can apply the Kit for 3 elements
quad on 50 Mhz band. The electrical features can be found on the
related page of this kit: 4 StQ 50 Kit
Adding this kit you will have a quad six bands full size on the same just
one boom.
Optional: " Rods elements Kit " 240,00 € (iva incl.)
When ordering the quad or even later
at the installation, it is possible to add the "Rods elements kit"
This option is made up of the following details:
- extension of the boom through a 25 mm diameter VTR tube
- Mastrant 3mm tie rod, which joins the elements together and then connects them
to the boom extensions
- one loop consisting of Mastrant 3mm, to be applied to all elements.
The installation of this kit avoids the movement of the fiberglass elements
during strong winds or snow and ice. The result is a structure that maintains
a correct level of flexibility to dampen the thrust of the wind on the antenna,
but never comes to overcome the critical level of mechanical stress.
Horizontal rod kit
On the models with 4 and more elements, we use an horizontal tie-rods kit, to prevent bending in the horizontal plane. In the very long antennas this kit is absolutely essential to have no problems in crosswind conditions.. It is provided a central aluminum plate on which is applied an aluminum tube 3 mt long; this pipe connect the tie rods Kevlar. All it made of stainless steel and alluminium.
