Overview

The T300B-S is a compact and rugged SOTDMA AIS Transponder with built-in Antenna Splitter designed for the demands of the small commercial boat fishing boat and leisure markets. It meets the Class B' (SOTDMA) standard allowing vessels that are not required to fit Class A' units to voluntarily fit an AIS Transponder.

When connected to an external VHF antenna and a GPS antenna (not supplied) the T300B-S will transmit its own vessel position and data and receive information from other AIS vessels shore stations and navigational aids within VHF range.

The built-in Antenna Splitter allows the unit to share a single VHF antenna with a VHF radiotelephone eliminating the need for a second VHF antenna on the vessel and reducing installation time and cost. Additionally the unit has an FM radio output for monitoring public service FM radio broadcasts.

The unit is initially programmed by the user with the supplied software over a USB interface. The T300B-S is compatible with a range of computer based navigation programs and chart plotters that accept AIS data sentences over a NMEA 0183 or NMEA 2000 connection.

fits like OEM
Style: PA99892
This fits a 2023 Civic Sport Touring without issue. It looks indistinguishable to the OEM filter. Getting the lid off the airbox is the hardest part as it is wedged in there pretty good. Other than that, this is a very do-able DIY job, and it's a lot cheaper than having the dealer do it. I have no concerns. Thumbs up.

Excellent Value, Easy to install
Style: PA99892, Style: PA99892
This filter fit perfectly! I have a 2023 Civic Touring with about 25,000 miles. I bought it new with 2 years of service, and when I went to the dealer for my last free oil change they wanted to charge me $135 to replace my engine air filter and my cabin air filter. Ouch! I have replaced air filters before so I knew it would be a fairly easy job. I was done in about 5 minutes and the filter material is as good as the original Honda filter I replaced.

Great product
These are very good filters and the price is great. I have found that replacing both these filters at the same time works well for me
