Unique form-factor

  • We really like the Discovery TX-500 Transceiver from Lab599. The PA500 is basically made for the TX-500 but it will work nicely with other radios as well. The thickness of the PA500 is just 30mm and allows you to operate from anywhere you like.

RF Low pass filters

  • The PA500 has separate low pass filter banks for the specific band regions. RF Filters made with superior ferrite toroidal cores and precision high voltage glimmer capacitors. The harmonic distortion suppression are >43dB below the carrier signal depends on the selected frequency band.

Robust aluminium unibody design

  • The PA500 body is made of CNC milled durable anodized aluminium, made for extreme operation, perfect for contest work on the go.

Integrated automatic antenna tuner

  • The PA500 has an integrated automatic antenna tuner for most of the operating frequencies to tune a suitable antenna between the 80m and 10m band.
