The JK801 is a motorized inductor coil loaded as well as end capactively loaded rotatable dipole, with a small footprint, giving great performance on 80M.
This antenna is made for the Ham operator that is looking for a compact dipole antenna to work on 80M. The best performance of this dipole is achieved at approx 130Ft or higher.
It is made with very high quality materials and the
best in its class in the market in terms of mechanical construction and electrical performance.
This Dipole has a good 40KHz bandwidth for each setting on the motorized inductor. The motorized inductor gives this dipole a full band coverage of 1:1 swr on 80M. This is achieved with a screw driver antenna type controller in the radio shack.
