The antenna is 30 feet X 4 inch irrigation tubing with 4 drop wires and 4-20 ft top loading wires with only 8 ground radiald 35-45 ft long could use a few more.

The unipole is grounded at the base making it less susceptible to lignting and buildup of static electricity.

The feed point impedance is about 190 ohms, making it a good fit for a 4:1 transformer.

I use this antenna on 80 thru 10 meters with the transceiver internal tuner including 60 meters.

The antenna can be converted to 160 meters by adding a 12 uh base loading coil (11 turns #12 wire on 3 inch PVC ) and 100 pf vacuum variable capacitor at the feed point.
