Trustpilot

The SIGNAL KEEPER base station antenna is an omnidirectional antenna made of aluminium alloy 6063 T832. It is factory-tuned at mid-band and allows for side mast mounting with the optional bracket FT-2 code 2510004.00.

Electrically, the antenna is a 1/4 λ base-loaded ground plane type operating within a frequency range of 26-28 MHz. It has an impedance of 50Ω, a 360° omnidirectional radiation pattern in the H-plane, linear vertical polarization, and a gain of 0 dBd and 2.15 dBi. The antenna provides a bandwidth of at least 850 KHz at SWR ≤ 2, with SWR ≤ 1.2 at the resonant frequency. It can handle a maximum power of 100 Watts (CW) continuous and 300 Watts (CW) short time, with a direct/centre feed system/position and UHF-female connector.

Mechanically, the antenna is constructed with aluminium, steel, and nylon materials. It can withstand a wind load/resistance of 36 N at 150 Km/h / 130 Km/h, has a wind surface area of 0.03 m², a height of 2370 mm, weight of 640 gr, and radial length of 640 mm. Designed for mounting on a mast with a diameter of Ø 35-40 mm, the SIGNAL KEEPER antenna is a durable and efficient choice for base station applications.
