Brand new range for 2018.
Vortex are happy to announce our new range of vertical antennas.
Here we have all the hardware to get you going with a brand-new 4 square on 40m using 4 quarter-wave length radiators.
All you need is the phasing box and plenty of ground radials!
Each antenna is a full size quarter-wave and comes with 6 telescoping sections (38.1mm, 30mm, 25mm, 20mm, 16mm and 12.7mm) of 6082-T6 or *AA6082-T6 aluminium tubing.

There is plenty of overlap on each section so tuning can be accomplished either at the low or high end of the band.

Tilt Over Mount
Each antenna includes a super heavy duty tilt-over mount.
Mounting is based around a section of 5 inch (127mm) channel stock x 1/4 (6.35mm) x 3/8ths (9.5mm).

The channel forms the support for the ground mounted tube which includes 2 x heavy duty M10 U-Bolts and stainless saddle clamps to fit a 2.5 inch (63.5mm) tube.
There is a large M8 bolt which forms the ground-bus to connect radials or a ground plane too.

The main radiator support is based around a 35cms x 3/8th inch (9.5mm) flat aluminium bar also in 6082-T6 construction grade material.
Using an extra heavy duty 6mm plated hinge at the base, the user can tilt the radiator element over with ease for any maintenance work.

The radiator plate is supported against the ground mounting by using two sections of 6.35mm x 2inch (50.8mm) 6082-T6 channel.
To compliment the system, we include 4 heavy duty Group 5 Stauff polyamide clamps which holds the main radiator solid.

An SO239 socket with a 6mm high-power copper link wire to the base of the radiator completes the line-up.
