The RV-4C is a well-constructed, durable antenna designed for multiple HF bands (40m, 20m, 15m, and 10m). It features the "Trap-Master" traps, similar to Mosley beam antennas, allowing efficient operation across these bands. The antenna requires a counterpoise, which can be implemented using radials, a ground net, or a ground rod. It stands at a height of 6.71 meters and supports a maximum power of 1000W, suitable for CW operations, with higher power ratings for FM (300W) and SSB (2000W). The antenna weighs approximately 4.2 kg and uses a PL connector for connection. It comes with documentation available in English.

Build & Performance Notes

• The Trap-Master traps are a standout feature, enabling efficient multiband operation without needing a tuner for most setups.

• Its low take-off angle makes it a solid performer for DX contacts, especially when properly grounded.

• Users have reported excellent durability even in high-wind environments, with some models still going strong after decades.

If you're considering installation, grounding and radial layout will make a big difference in performance. 

• Radials: All three benefit massively from a good radial field. For best results:

  • Use at least 20–30 radials, each 3–10 meters long.

  • Lay them out like spokes on a wheel.

  • Use lawn staples to secure them if burying isn't an option.

• Grounding: If you’re in an area with poor soil conductivity (like sandy or rocky terrain), consider adding a ground rod or mesh net to improve performance
