Hy Power GU9-HF-50
The GU9-HF-50 is a 9 to 1 beverage transformer with an SO239 connector for coupling your coax and dual banana jacks for connecting beverage and ground. The grounds are independent for input and output.
This transformer maintains a flat SWR curve over the entire HF frequency range when terminated into a 450 ohm matched load. It is designed to be used with beverage antennas but can be used with a transmitting antenna. It uses dual ferrite cores and can handle up to 200 watts in a matched condition. These ratings are good up to a 2:1 SWR.
The enclosure is not waterproof and is not meant to be left in the outside elements uncovered. When used outside it must be placed inside of a waterproof enclosure. If this transformer is used on an antenna, such as an antenna used for portable or field day operations, you must provide a means a strain relief. The connections on the transformer are not strong enough to handle the mechanical stress from the antenna wires.
