Celwave RFS 638-6-4-3 UHF Ham 435-470MHz 100W Duplexer Cavity- Free Shipping 

Tested good using an Agilent E8285A service monitor. 

Size is 25 x 23 x 4.5cm. 

It is larger than the common 6 cavity duplexer as in the photo. (The smaller one in the photo is not included in this sale.) 

I can also set TX & RX frequencies you want using my Agilent E8285A service monitor in the photo. 

List price for the new one is around $3000-$5000 range in the market. 

I am selling this at a much lower price. 

I ship via airmail that takes 7-14 days to most parts of the world from Korea. Some remote regions may take somewhat longer.
