The inverted rhombic antenna boasts a distinctive half-rhombic configuration. Its directivity focuses toward the terminated end, enhancing signal precision. Developed by Bruce, it demands a non-conductive mast for optimal performance. This design delivers significant gain across the 50 to 70MHz bands.
A non-inductive terminating resistor is essential, tailored to the RF power delivered. For SSB use, a lower wattage resistor suffices. Reception-only setups allow flexibility with resistor types. Staking ensures structural integrity, while a sturdy pole provides elevation. The trans line seamlessly integrates the system, optimizing functionality.
Half Rhombic antenna with counterpoise was published in RSGB Radio Communication magazine December 1996 page 62.
