Tuning box for 30/15 meter vertical
3 of 4
The network is mounted in an 8x8x4 Carlon outdoor box. RF arrives via a SO-239 in the bottom of the box and exits via a ceramic feedthrough insulator at the top. There is also a 7 pin Hirose connector for relay control and a 1/4-20 stainless bolt for grounding. The ground system currently consists of eight #18 insulated radials just below the grass (not buried). Four are a quarter wavelength on 30 meters and four are about 0.15 wavelength on 15 meters. There is also a 5-foot copper clad ground rod.
