RM - HLA300V Plus

Product code: 1782

The RM HLA300V Plus 'black line' is a HF broadband linear amplifier with protection against polarity inversion, excessive temperature and excessive R.O.S.*. The max. output power off the amplifier is 300 Watts AM-FM and 550 Watts SSB (PEP) and is equipped with 3 cooling fans.

The amplifier is just studied for meeting the need to increase the power of the decametrical apparatus in low power (Yaesu FT817 and Icom IC703 etc.), keeping high the features of attenuation of unwished outputs (harmonic distortion) to effect long and very long distance connections. It works on all amateur radio HF brands 1.8-30 MHz meters in every working mode. It features a series of Low-Pass filter with 3, 4, 5, 8, 15, 22, 31 MHz cutting frequencies to drastically break the harmonic output power.

*Protection circuits are not 100% guaranteed. To prevent damage to your amplifier always check your VSWR after changing bands, no hot switching, no excessive input power etc.

Frequency range: 1.8-30 MHz
