An amplifier device for amplifying RF communication signals compatible with IEEE 802.11 standards. An amplifier circuit is housed within a cylindrical metal housing that provides excellent heat dissipation and requires no mounting hardware for installing the device within a communication system. The metal housing with an integrated lightning arrestor creates a watertight seal to protect the amplifier circuit from damage when installed outdoors and the amplifier circuit is compatible with both 2.4 GHz and 5.8 GHz frequency applications.
