Need a high performance, multi-band, stealthy antenna system that is easy to setup and use? Get the Bullet-9 matching unit, the antenna wire and insulator all in one convenient package (great for HOA restricted areas, camping and portable operations) and remember to add the feed line choke. Multiple lengths available depending upon bands coverage desired and choose 100, 500, 1500 and 5000 watt power levels.
