Customer Comments:

"Hi Justin,

I offer the following anecdote and with a request of help and advice.

Last September I arranged with you to acquire a 6m 8el OP-DES antenna. The antenna assembled easily and went to the top of my tower within a few weeks after arrival here in Arizona. It has been up at 90 feet for the past many months with great success.

In the time I have had it up I have achieved the following on 6m:

WAS

493 grids worldwide

331 grid within the US 48

56 DXCC countries

23 cq zones

.. and the most recent achievement was a successful 6m EME contact with N0TB and a near miss with a station in Japan. See attached screenshot of the N0TB QSO.

I have received email from European stations telling me I was the only signal from North America they could hear on 6m FT8. I have put Vietnam in the log too. I joke that I am doing meteor scatter with MSK144 off of dust.

All I can say is what an outstanding antenna!

All the best,

Chuck

Specification

This antenna is made with 5.8 inch (15.88mm) centre elements and 1/2 inch (1.27mm) outer elements with the OP-DES end sections 3/8 inch (9.525mm). The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts. Boom is 1.75 inch (44.45mm) square 10 SWG aluminum (3.2mm wall).

Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, ensuring they work as well as our software model predicts.

Note: Much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make up of our antennas have least effect on performance and pattern degradation. More information can be found here
