VHF ANTENNA (Sirio GP 160 LB)

Definition

Wide-band VHF antenna for base station.

Allows omni-directional transmission and reception over a wide range of frequencies.

Specifications

  • type: 1/4 wavelength ground plane large band
  • frequency range: GP 160 LB: 145-175 MHz at SWR <=2 impedance: 50 Ohm
  • radiation (H-plane): 360° omnidirectional radiation
  • (E-plane): beam width @ -3 dB = 78°
  • radiation angle: 0°
  • polarisation: linear vertical
  • gain: 0 dBd - 2.15 dBi
  • maximum power (CW) at 30°C: 1000 watt

Instructions for use

Before installing the antenna, the radio must be turned off and the power cable must be disconnected.

Instal the antenna at the top of a mast, as high as possible.

You may use a mast on which a folded dipole HF antenna is already installed, provided there is no contact between the 2 antennas.

The antenna can be attached to the mast in two ways with the mounting kit supplied:

  • either at the top of a 40 - 54 mm diameter mast (the connecting cable runs inside the mast)
  • or laterally at the end of a 20 - 54 mm diameter mast (the connecting cable runs outside the mast); in this case, attach the cable to the mast to prevent the connector carrying the weight of the cable

Be careful when raising or lowering a mast equipped with an antenna, as the radials of the antenna are easily damaged.
