    Thank you for watching what ever amount of the video you did watch as always it's free to watch and you can stop at any time you like. I enjoyed making the video and making a few contacts with a new antenna out of the bag and got got a great tan. Just posted a DMR video on my channel that's free to watch also:

    Jim, I think that wire would be more correctly called a radial wire and it's main function would be to be a counter-poise to the radiating element. Yes, there might be a small, but very small bit of directive activity mostly in the direction the wire is pointing. The amount would vary by band, being more pronounced the higher in frequency that you go.

    Near Vertical Incident Skywave antennas work mostly on the low bands (below 8MHz) and depend on the signal direction mostly going straight up and being reflected almost straight back down again. This gives reliable local communications. In the video, you can see that the wire is way too low to be anything more than a radial, which helps the antenna to radiate and maybe be easier to match. Very little if any useful RF energy is being radiated from that wire.

    But, if its all you have, then by all means have at it! After all, a poor antenna is still much better than no antenna!

    Interesting stuff--I went to the mfg site to see what they said about the NVIS element and this is what I found---learning stuff every day!

    "Specifically designed for the Alpha Vertical & EzMilitary (TM) Antenna systems, the "NVIS Kit" from Alpha Antenna includes one element that adds horizontal polarization to your Alpha Antenna system. The kit enhances performance on all HF frequencies and also enables NVIS on the bands that very much depend on horizontally positioned active elements (40 & 80 meters)."

    Sounds like they are saying its a combo of a "radial" as you mentioned, and provides NVIS capability on the lower frequencies as well.

    Anyway, I plan to use it in the field again in the next week or so, as I have a new field transceiver to shake out.

    Look at the two going at it! A pair of trolls and both will fight for the last word.:eek:

    It seems to me the makers have no right then to claim this product is a "military" antenna.

    Not sure why. The term "military" is pretty genereic. According to their site, they sell "military style" antennas---probably its individual portability is why they call it that. Kind of a minor detail.

    Can't be any worse than describing an antenna as a "bazooka" lol.
