These antennas are came on the market exactly once, about 10 years ago- and then they were gone. As a ham radio operator myself (W4WTF) I kept one and love it and was always looking for more but they have never come available again. Cleaning the warehouse we found 3 more from when we had them before.
These antennas are a discone type antenna on steroids. The specs for them say they are designed for 30-78mhz because that is the standard military VHF-Low range, but testing on the one I kept for my own use showed an SWR of less than 3:1 from 25mhz to over 160mhz in my installation, being a discone they are very broad banded. You can change the number and length of the elements to adjust the frequency range as they screw into each other. I have run them with a tuner down to the 40m band during field day before and was surprised how well it did.
These kits have a 33+ foot tall mast, the antenna center hub, guy wires, stakes, and coax- everything you need. It all comes in a storage case that has a shoulder strap. Under 40 pounds for all this makes it a great portable unit. You can set them up quickly with one or two people.
Only 3 are available. Not available on the website, to order one respond to this email with your address for a shipping quote.
$375 each
Note in this last picture we did not have all the mast sections installed, there are 3 more at the bottom that can make it even taller.
Once again, there are only 3 of these available. They are not on the website, respond to this email to get a shipping cost quote or claim one and we will complete the order. Do not call- we are doing this email only to ensure the first people who respond get them fairly.
