For development projects and amateur radio operators have often the problem, how test an amplifier without sending the energy into antenna. For this problem exist an solution, Dummyload systems to absorb the energy and convert it into heat.

We look at the market and saw, all dummyload systems with higher power levels are very very expensive. We start the development to find solutions with excellent datas and acceptable prices for private amateurs. The overview below show the current available models in power ranges from 250 - 3000W rf power and frequency ranges up to 2,7GHz..
