    Great presentation. Only thing I would disagree with is the most "hazardous" band. You said 30 to 300 MHz is the most hazardous. It needs attention but in my opinion the most hazardous would be the 13cm / 2.3 GHz band. It's still non ionizing radiation but is very close to the frequency that excites water molecules which is where your microwave oven operates at. You definitely don't want to be standing in front of my 13 cm 23dbi gain Yagi at 250 Watts transmit power. I could definitely warm your body at those power and antenna gain levels. Mike KC3OSD

    i bought 2 tacticals vhf/uhf antennas and both was out of spec (swr > 2.5 and away of the center of the bands).. those antennas are now returned (from amazon).. the only one better than my rubber duck i have found is the NA-771..

      I got tactical 47 inch I think from ebay called TCA PRC-152A. Supposedly the base is Harris. I put antenna under rig expert and it good fair low SWR everywhere from VHF to UHF. Got 2 of them and both measured good. They work great.
