The PROex138-10-Q-0 has been specifically engineered to meet or exceed all the requirements of a broadband, offset dipole professional grade antenna.
This antenna provides 10 dBi gain and operates effectively across the frequency band of 138-174 MHz with a VSWR of 1.5:1 or less.
The dipole to mast spacing is 1/4 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 PROex138-10 is made standard with 5' of RG213 cable with a soldered N-male crimp connector.
