This Telewave watt meter is mislabeled as a model 44A but is actually a model 44AP as it includes the factory installed -40 dB sampling port on the side. The frequency range is 20 through 1000 MHz with variable wattage range of 5, 15, 50, 150 or 500 watts at 50 ohms. The input/output connectors are 'N' connectors. I will include a pair of N to SO-239 adapters for your convenience. The original manual is also included. This meter is in near factory new condition, has had very little use, is clean and from non-smoking environment. These sell for $1000 or more. I'm selling this one for $500 for local pick up or plus $15 if I need to ship. Item will ship out from SW Idaho once check clears the bank. I don't use Paypal or any other electronic method to receive funds. Please inquire via my listed email on my QRZ page.
