In The Beginning...
Your getting a look at some of the materials that are being machined in my shop, as part of a new 10 thru 80 meter HF antenna.
This antenna will be quite unique, as I have not seen another of its type available in the marketplace.
Whats different about it you ask....Well if you look close, you will notice the assembled mast assembly is of two different diameters.
As the photo shows, the mast assembly (the length of the lower mast will be somewhat shorter than in the photo) is sized for a 3 inch coil at the top end of the mast assembly, but the lower section of the mast is only 1.375"OD. When the antenna is complete, the coilform will consist of 2 different sized diameters, allowing for the upper 3 inch section of the coil carrying the tinned buss wire & the whip, to be stabilized by the lower Delrin endcap that will reside within the lower mast.
When operating on the lower bands such as 80 meters, this will allow for a very well supported 3 inch diameter sized coil, although with a pleasing overall appearance due to the smaller sized lower mast.
Stay tuned, I'm in the shop making chips.
