School me on the EDA2400

[BigLebowski]

I apologize if this is stupid question, but in researching different multicoupler solutions, I am left with a few questions. My knowledge of multicouplers is lacking.

I was originally planning to buy an Stridsberg multicoupler, but in reading some various posts I am seeing that while nice, they may be a waste of money for my application. I am now looking at the Electroline EDA2400 and/or 2800. I will be feeding 2 Homepatrol 2's into this and maybe a couple BCD996XT's.

My main questions are:

1) I see that power is fed into the EDA2400 from a wall wart via coax, and that power is present on the output of one of the ports. Is is still okay to connect a scanner to this powered port or should I just use the other 3 to avoid damaging the scanner?

2) Is it necessary to terminate the unused ports with a dummy load or some kind?

Thanks!

1. That port is an optional way to power the unit. So it’s a power input, not output.
2. I always terminate unused ports to keep out stray RF….but that’s just me.

Thanks! So just confirming that the "OUT1+PWR" on the bottom left doesn't actually have any power, that is just an optional power input?

Yes. Find the sheet online and it will show how to use it.

Keep in mind the 4-port versions have around 7.5 dB gain. Sometimes gain can be a bad thing.

I’d lean toward the 8 port at 4db gain instead. I have tried the 7.5db splitter and it was too hot for the scanners. It overloaded the front end especially on GRE scanners.
