Please contact our sales staff for alternate connector requirements. Extended feed line available in 5’ increments up to a maximum of 50 '. All extended feed line antennas equipped with LMR400 cable and N-Male connector. The PROex138-7 has been specifically engineered to meet or exceed all the requirements of a broadband, offset dipole professional grade antenna. This antenna provides 7 dBi gain and operates effectively across the operating range of 138-174 MHz with a VSWR of 1.5:1 or less. The dipole to mast spacing is ½ wave. All WaveLink Antenna PRO Series offset antennas are manufactured using high strength 6061 T6 aluminum to ensure consistent operating performance. Each dipole junction is welded in a fixed position, incorporating a tuned, internal cable harness, thereby eliminating any exposure to the elements; every broadband dipole is fixed in place by a CNC-machined aluminum saddle. These two features combine to minimize or even eliminate all potential intermod or misalignment problems . In addition, the dipoles are anodized to protect against environmental degradation. The PROex138-4 is made standard with 5’ of LMR400 UltraFlex with a soldered N-male crimp connector. Suggested mounting bracket C1002 (Bracket not included)
