In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

Yes. The AT-1108/ARC will directly replace the original Collins 37R-2U. Although there is no official documentation stating their interchangeability, one can view the functional and physical specifications for each and determine that they are exactly equivalent. Both have separate coax connectors for VHF and UHF connection. Both have the same hole patterns or footprints.

Most importantly, a New condition RA Miller AT-1108/ARC is available at a fraction of the price that the Collins 37R-2U is available on the used market. It should be noted that some of the used 37R-2U available on the market could be over 30 years old.
