Iskra P-18/400 is an 18-element log-periodic directional antenna for outdoor installation. It covers the 380–500 MHz range and suits the 380–400 MHz frequencies of the VIRVE network as well as TETRA and LTE 450 networks.
The antenna suits fixed sites where the connection needs to be directed in a specific direction. This model is supplied with a 0.3 m pigtail and an N female connector, so a feeder cable of suitable length can be used for each site.
Features
- Directs the connection: 10 dBi gain and a 21 dB front-to-back ratio favour the chosen direction.
- Wide band: the same antenna works across the whole 380–500 MHz range.
- Easier alignment: the main lobe width is 80° horizontally and 60° vertically.
- Ready to install: the antenna is pre-assembled and the pigtail is already attached.
- Vertical or horizontal: the supplied mounting bracket allows installation for vertical or horizontal polarization.
- Built for outdoor use: made of aluminium alloy, galvanized steel and UV-resistant plastic.
