4.5 dB Phasemaster Roof Mount Antennas TM 400-520 MHz CSW10 Series CSW20 Series The CSW10 and CSW20 Series, the original PhasemasterTM antennas, are our most popular roof mount antennas due to their unmatched performance and superior strength. The highly flexible stainless steel whip and consistent 4.5dB gain has made them a favourite in virtually all roof mount applications. The outstanding performance of PhasemasterTM antennas is attributed to their unique construction. At the centre of the whip is a precisely matched phasing coil separating the two electrical elements. The combination of these elements (a 5/8 wave over a 1/2 wave) delivers 4.5dB of gain when centre roof mounted. The strength of PhasemasterTM whips is a direct result of simplicity in design. The entire colinear assembly is air wound from a single length of 17-7Ph stainless steel for superior flexibility and resistance to permanent bending. The antenna will stand up to knocks and blows and will always bounce back, time after time, to its original shape. The air wound coil adds additional durability by acting as a spring to absorb bumps or knocks. The antennas are available in the classic stainless steel finish or with a black high gloss finish. The antennas are supplied in colour coded bands and are then tuned in the field to a tuning chart supplied with each CSW24 CSW14 antenna. • Australia's most popular roof mount UHF antenna • Superior 4.5dB Gain • Flexible 17-7Ph stainless steel whip will always bounce back after knocks and bumps • Attractive - Clean elegant lines compliment vehicle styling - in black plated or stainless steel finish • Rugged air wound coil absorbs the bumps and knocks www.rfindustries.com.au R-26 4.5 dB PhasemasterTM Roof Mount Antennas 400-520 MHz CSW10 Series CSW20 Series TEST FREQUENCY: 460 MHz 0° 0 REFERENCE ANTENNA 330° 30° 5 MODEL: SW7 10 MOUNT: MB10 Typical VSWR Response 15 POSITION: Centre Roof for CSW14 300° 20 60° 25 TEST ANTENNA 30 MODEL: CSW24 35 MOUNT: MB10 270° 90° POSITION: Centre Roof This pattern shows that the PhasemasterTM antenna is meeting the gain and omnidirectional 240° 120° performance we have stated in our specifications.
