The image below shows the structure under test. I wanted to make sure it was secure and strong enough.
It is being supported on my heavy duty tripod, which has a 4m mast attached.
The below image shows the centre plate with the four spreaders attached.
You can also see the extra sets of holes. to attach more poles to support a Delta loop.
I have added crocodile clips to the ends of the poles. This can support a tension line or radiator.
Below is a picture of the centre plate and four telescopic fiberglass spreaders.
The clamps that hold them in place are for car exhausts. They come with the U shaped metal supports. reducing crushing of the fiberglass poles. The poles are 4 meters long when extended. So it will support a 20 meter antenna.
I decided to build a portable and light frame for a HF Moxon or Delta Loop Antenna.
HF Moxon / Delta plate
Above you can see the centre plate. It is 1 CM thick Perspex. Its dimensions are the same as a4 paper. They are sold on ebay for a few pound. very cheap, strong and light. perfect for portable use.
There are holes drilled for four spreaders, these are to support the moxon.
There are additional holes drilled that allow me to remove two spreaders and fix one perpendicular to the plate. This creates a very large triangle to support a delta loop.
