The RFI CD63-71-73 UHF CB Mopole Antenna stands out for its remarkable performance. This innovative design allows for the end feeding of the collinear whip section, enhancing signal reception. The antenna features a 5/8 over 1/2 wave radiator crafted from a single piece of high resilience 17-7PH stainless steel, ensuring durability and optimal performance. Designed for versatility, the CD63 antenna offers true ground independence, allowing it to be mounted in various positions such as vehicle mirrors, gutters, or roof bar mounts. It exhibits an impressive 6.0 dB gain over a ¼ wave whip when mounted in the center of a metal roof, highlighting its excellent performance. The stainless steel whip is flexible and returns to its original shape after bending, while the base coil, housed in a high-impact thermoplastic molding, ensures rugged durability. The antenna's stylish black finish complements vehicle styling, making it a practical and attractive choice for UHF CB communication needs.  CD63 antennas demonstrate a notable 6 dB improvement in received signal level in practical field conditions compared to a ¼ wave whip. However, in pattern tests, they only show a 1.5 to 2 dB improvement over a ¼ wave, which is equivalent to 1.5-2 dBq. This enhanced performance is due to the lower radiation angle level of these ground-independent antennas.
