Now that I have an external antenna, I was looking at upgrading from a BNC "T" splitter to something more useful. How much difference is there really between the amplified and passive models? $100 extra is alot to me. I want to run 3 radios off of one discone 20' in the air. I like the Stridsbergs, but $185? The I.C.E. units only have a range of 30 to 500 mhz. Are there any other multicouplers that anyone has used for a more reasonable price?
