Diamond CP-8040 Dual Band HF Vertical Antenna

The Diamond CP-8040 is a dual band high frequency vertical antenna. It is compact, lightweight and very easy to assemble. It is completely self-supported and does not need any guy wires. Trap radials could be concentrated on one direction instead of spreading them around the antenna. This is especially convenient if the antenna is installed on balcony railing or window side of condoniums and urban apartments. Since the antenna is direct DC ground at the feed point, coaxial cable and transceiver are being protected from the high voltage caused by lightning. Centre frequencies of the antenna are adjustable in each band simply by change radial length and capacity hat (80m only). Top loading structure utilizing capacitive hat enables the antenna to complete with full quarter wave length antennas in its performance. It is rigid and rugged enough to withstand the wind pressure over 35m/sec. Mast brackets area adjustable to accept 1 1/5" to 2 1/3" diameter mast. Since feeding point is covered by the support pipe, it is excellent in the waterproof property.
