    Installed my Sirio NV 4000


    • Hello, very pleased with this antenna. Instructions were brief and easy to understand. I used an online calculator and converted the measurements to standard and put together. I did not have to do any other adjustments from there as my SWR was 1.1 with the antenna laying on a sawhorse, and when stood up, it measured 1.05 on channel 14, my standby channel. My measurements were L1 36 5/8, L2 25, L3 28 3/4. I am currently 30' to my feed point, but will soon be 56' foot to my feed point. I am very pleased with the improvement in my receive, unsure how much is due to the lower receive noise and how much is due to the antennas ability to just plain hear better, but it doesn't really matter. It seems to be well built from what I have seen and hope it will last a long time. I also used rubber tape at all the joints not so much for water-proofing, as I did to help stop any screws from backing out.

    I will take pictures of the antenna when it goes on my tower. It is on my push-up pole right now. It has lower noise, much lower back ground noise than my Imax and as good and many times stronger receive signals than it does. My Imax's feed point is currently at 56' and the NV 4000 is 30'. I am looking forward to hearing the improvement when it gets put on my tower at 56'.

    It's working great and reports indicate about 2-3 s unit increase in signal strength.

    Awesome antenna!
    I'm experimenting with a 2 meter version. Just started on it today. Trying to use a cap hat and direct end feeding (no gamma). We'll see what happens.
    Love your antenna.
