The EMCOMM III Base antenna, is an effective multi-band High Frequency (HF) antenna specially designed for short to long range base station HF communications. Due to configuration and installation flexibility and low visibility design, it is ideal for home use even in developments with a Home Owners Association (HOA) and Covenants, Conditions, and Restrictions (CCRs). It is also highly suitable for military, government agencies, non-governmental organizations (NGOs), Military Affiliate Radio System (MARS), Civil Air Patrol (CAP), Amateur Radio Emergency Service (ARES) / Radio Amateur Civil Emergency Service (RACES), Salvation Army Team Emergency Radio Network (SATERN), and shortwave listening. The EMCOMM III Base antenna is configurable to facilitate both long distance (DX) and Near-Vertical Incident Sky wave (NVIS) communication and using an automatic antenna tuner or coupler with memory settings will support most Automatic Link Establishment (ALE), frequency-hopping, and spread- spectrum modes and operations. SWR: Subject to frequency and configuration, but typically less than 2.7:1. An antenna tuner or coupler may be required depending upon frequency and configuration. The EMCOMM III Base antenna can be installed by the operator in less than 30 minutes. It should be installed as high and straight as possible, but almost any available supports, such as an existing antenna tower, trees, a flag pole, the eaves of a house, or a non-conductive fence can be used with satisfactory results. The EMCOMM III Base antenna is comprised of a matching transformer and a 130 foot antenna wire on a line winder - making an effective HF base station antenna system for permanent installation as a primary or backup HF base station antenna.
