Description
Features: The folded dipoles utilize an internal phasing harness in stable, PTFE-based double-screened coaxial cable with PE Jacket for optimal weatherproofing. These elliptical arrays incorporate extensive sidelobe suppression, null fill, and accommodate power input levels of 750 watts continuous. With all-welded construction and superior internal harness construction, these antennas provide not only excellent radiation characteristics but also high levels of intermodulation and noise suppression. The entire array rests at ground potential and offers the ultimate in lightning-resistant antennas. • High gain elliptical pattern with 5dBd or 8dBd versions available • Operate over entire 136-174 MHz band without tuning or adjustment • Inverted mounting version available • Industry-leading PIM ratings (-150dBc) providing low IM and low noise characteristics for optimum performance Options available include: •All stainless steel 316 grade construction (5dBd array only) •Inverted mounting configuration •EA40-41 may be operated as 2 x 5dBd arrays by removing external cable harness (1) Factory pre-set downtilt of 3° may be specified on EA80 series antennas using model no. trailer -T3 (2) EA40 series can be optionally supplied in all welded 316 grade stainless steel. Dimensions vary slightly (3) Connector termination option available of 7/16 DIN female connector using model no. trailer -DIN
