Descrizione
Broadband, Conical, Weather proof, suitable for sea applications RADAR Absorbent Material.
Conical Rubber Based Radar Absorbent Material (RAM)
- At Normal Incidence & Upto 45o from Normal: Min. reflection loss (angle of incidence equals angle of reflection) w.r.t metal plate of same size shall be -15dB at 5.0 GHz, rising to min. -17 dB at 8.0 GHz and min. -20 dB at 10.0 GHz and higher frequencies in both polarizations.
- At 60o From Normal: The reflection loss is down by less than 5 dB w.r.t normal and upto 45o performance at all frequencies and in both polarizations.
- Under Wet Condition: Performance under wet condition remains practically unchanged w.r.t dry condition performance at all angles/polarizations /frequencies.
DESCRIPTION
