These popular omnidirectional antennas have been selected for use with repeaters, talk-around systems, paging systems, security alarms, VHF dedicated systems, 220 trunking systems, and in such applications as police, fire, agricultural and hundreds of others requiring reliability, long life and economy. Field tunable and easy to install, they can be mounted on any vertical tubular support up to 1-1/4 inch (3.2 cm) diameter. Ringo, Ringo Ranger, and Ringo Ranger II can be shipped economically by UPS. Our most popular base station antenna is now available in the 220 MHz band. Both the CRX- 220B (220-222 MHz) and the CRX-150B (150-174 MHz) feature a full 6 dB gain vs. a quarterwave antenna. The Ringo Ranger II is perfect for trunking or any other system where ease of installation, performance and economy are priorities.
