 Outdoor Longwire Shortwave & MW Antenna

The Outdoor Longwire Shortwave and Medium Wave Antenna significantly enhances reception of signals in the medium wave (MW) and shortwave (SW) bands covering 0.5-30 MHz. This antenna is based on a 10 metre longwire antenna design but provides significantly improved reception over a basic longwire because it utilises a matching transformer that acts as a balun with a ratio of 10:1. This provides an optimal match between the 500 Ω antenna and the 50Ω input of the external antenna input of most shortwave radios greatly increasing the amount of signal provided to the tuner. 
The antenna’s 7.62 metre coax feeder acts as a counterpoise for the antenna, therefore no connection to ground is necessary. However, the stainless steel eyelet which is connected to the balun is internally grounded, so if reception is noisy this can be grounded to an external earth. The RG-174 coaxial cable is terminated in a mono 3.5mm plug that suits our portable shortwave receivers with 3.5mm antenna input and our desktop shortwave radio with BNC antenna connection. The antenna is omnidirectional and can be used indoors or outdoors and is completely waterproof.
