Aviation HF Intl. have been in the HF Aviation business for some 40 years, understanding the fact that to install a TSO'd hf radio system in an airplane the average cost for used equipment with installation is around 95, 000. to 150, 000. We have come up with the solution for this problem with our portable hf radio system, because its completely portable and we are approved under the FAA's (PED) portable electronic devise rules, the same rules that devises like the Garmin 796, 696 GPS. The Ferry, corporate, and private pilots as well as manufactures like Cirrus, Cessna, and Hawker Beechcraft are using our radio systems. Our radios are being used at NASA, and we are approved in many countries like Israel, Indonesia, Brazil, and Australia just to name a few, we also offer different antenna options as well as a on site supervisory installation service to make the installation easy and painless. When the installation is done you can rest assure that it is done right and it works well. We can be reached at firstname.lastname@example.org or 815-409-5070. Have a great day.
