Gray-Hoverman GH10n3 with NARODs for UHF/VHF-hi


This antenna is the first model of the series GH*n3 models. The difference with my earlier gh10s is that this was optimized with 3 narod reflectors from the start. I decided to begin with the biggest configuration since I already have some smaller models completed. The antenna has a minimum of 14.45 and an average of 15 dBi UHF gain. The VHF-hi gain ranges between 9.4 and 10dBi with an average of 9.7dBi .

The model is result of running the nec.opt script. The wire is 1/4 inch diameter 6061-T6 aluminum. The impedance is 300 Ohm
