Description
This listing is for the complete antenna hardware to make a 4-square for 40m. Not supplied is the phasing lines or the switchbox. You may either make your own or purchase the pre-made 4-way 4-square from Array Solutions (for example).
What’s in the box:
- 4 x 10m DX Commander telescopic poles
- 4 x Ground Plates
- 4 x Radiating Plates (optional but it makes the build more elegant)
- 4 x Retail Guy Plates
- 4 x DX Commander SO239 assemblies
- 28 HCL Clamps as a stay-up kit
You will need some guy lines and your elements / radials including 6mm hardware (nuts, washers bolts etc). For the upper top three or four sections that are under extrtemely low downward force, instead of HCL clamps, you can use tape and a zip-tie or for permanent use, suggest a dab of gel-based super glue rather than a clamp (warning, this is normally permanent).
Use any wire you wish. Suggest insulated equipment wire and use 16 x 1/4 wave radials or 30 x 1/8 wave radials for effective results.
For fine tuning, cut a longer piece of wire as your element, say about 11m long and fold the extra length back down the pole (once you reach the top). Trim for exact 1:1 match on each of the 4 x poles before connecting up your 4-square switch box.
Mildly helically wind your element up the tube and secure it periodically with some Temflex tape. It stops the wire flapping about. Secure with tape.
