H-422
40/20/15/10M Quad-Band Trapped Dipole Antenna
Features:
1. New compact design for even the most restrictive mounting locations, providing
wide band-width in a small footprint.
2. Assemble as either a “straight” dipole, and/or in a “V” configuration. When
assembled in the “V” shape, good performance is provided even from a minimum
height of only 10 feet!
3. CBL-2000 high power 2kW/SSB balun is included, and helps to prevent TVI and
other interference.
4. Specially designed high power traps assure constant high power QSOs
5. Three radiator lengths - Low - Mid - High – are illustrated for easy tuning.
