Looking for a 10 Watt in-line RF Power Limiter with a BNC male and a BNC female

I am looking for a 10 watt in line RF Power Limiter with a BNC male and a BNC female.
I need to put this limiter in line to my Garmin Asto 220 to limit the in coming power to 10 watts
Does anyone know there I can get one?

Hello there:

your specification is not adequate.
A limiter is specified with a maximum input power, a maximum output power (leakage), frequency range, response speed.
Specifying connectors is NOT enough!

There are a ton of limiter manufacturers out there. A good low cost one is Herotek.com
