40m Add-On Dipole (pre-assembled) for HEAVY DUTY Spiderbeam Yagis

This version is pre-assembled and ready to install on a Heavy Duty Version of a Spiderbeam Yagi. (Balun not included.)
It can be attached to your existing 3- or 5-band Spiderbeam Yagi antenna. (Except for the special WARC version)
The dipole is mounted offset by 90 degrees to the existing wire elements.
Both sides of the boom are extended by an additional fibreglass tube, increasing the turning radius from 5m to 6m.
Each end of the dipole is capacitively loaded with two thin wires that are connected to the lateral spreaders.

Scope of delivery/material list:
- 2 Fiberglas Stecksegmente (HD Yagi version / 30mm diameter)
- Plastic cable spool for winding up the dipole during transport (20 cm diameter)
- 2 Stainless Steel Hose-Clamps
- Prefabricated dipole consisting of:
-- Wireman CQ-532 Copperweld Wire
-- Enamel-Insulated Copper Wire 1.5mm dia.
-- 2 Special Coil Forms
-- Polyethylene Insulators, black, UV-resistant
-- M6 Tubular Solder Lugs, galvanized and tinned
-- PVDF Monofil Line, 1mm diammeter (UV-resistant)
-- Heat-Shrink tubing with hot-melt-glue inside

The dipole may be connected to the Spiderbeam’s existing balun and used with the same feedline as the other bands, or used with a separate feedline and balun.
Alternatively, a separate feed line and a second balun can be used.
When using only one balun, the forward gain and front-to-back ratio for the higher bands are not affected, but the front-to-side ratio is reduced, especially on 15m.
The (optional) balun is not included with the dipole and must be ordered separately when 2-balun configuration is desired.
The balun is available either in kit form or pre-assembled and ready to install.

NOTE: Not compatible with the WARC Spiderbeam Yagis.
