7MHz MicroVert by JA1SCW

This web page describes the MircroVert for the 40m band. The length of the radiator is only 143cm and the length of the coax cable for the counterpoise is 8.3m. You need to attach the 29.4uH coil for the radiator and the choke coil of the FT240-43 between the counterpoise and the coax feed to the transceiver.

The antenna is quite small for 40m band and can install it on the small space. I've made one for my QRP rigs and have a good performance to the domestic CW communication.
