Wells only good on 10,15,20m and needs a tuner so  I am sure it will radiate. They mention military antenna. Military has never been known for high gain, just functional. I am sure it will rediate and for $150 might be usable but there are many other options and cheaper ones at that.

Don't worry about it.  The antenna will be lossy enough to have a quite flat SWR. Wink

For detailed description of my decision to use the Alpha MOTO, may I refer you to my review that I just posted about the Alpha MOTO mobile/multiband HF/6 antenna. I suggest that you check my QRZ & LOTW logs to confirm my QSOs and QSLs, including my SSB calls from CT to CA, PA, IA, FL, MS, SC, Bulgaria, Crete, Czech Republic, & Italy. But don't forget to compare how I designed and built my system versus the abbreviated build processes that some folks use. My QRZ bio/profile page has link to my YouTube mobile build series videos. I did a LOT of design and prep work, plus grounding and bonding, before mounting the Alpha MOTO on SS brackets, 2 feet inboard and OVER the body mass of my SUV, to improve ground plane. Let me know whether you think I hit my objectives by integrating the Alpha MOTO into my design. I'll let the results speak for themselves.

I have ZERO complaints, to date.

N6BT, everything works including a light globe. I did try this and it does indeed work. It sure was a lousy antenna.

Every video on Youtube about the Alpha Moto Antenna shows station claiming what a great antenna it  is by demonstrating the short skip contacts they making. One hop QSO that are  all 5/9 plus.

The Alpha Moto is in the same class as the Maxcon and Other resistor terminated antennas. These also work. I have used commercial T2FD style communications antennas like the Codan, Barrett and B&W loaded antennas. They work too, however when I compared them to a good dipole they were clearly in the ESP/Dummy load category when trying to work DX.

I even have a highly efficient based loaded Codan 9350 which was compared to my bug catcher which was easily 6 to 12db better on almost any frequency.  This gain deficit is easily understood. A hamstick would be a better choice on most occasions.
