Can I bump this? What happens if I'd use a 75Ohm barrel instead of a 50?

Presuming this is for a receive application and you use the current spec 75 ohm adapters (where the pins/jacks are the same size as 50 ohm connectors), all will be good; there'll be no losses of any significance.

It's indeed for receive. Thanks. I was under the impression that it's a close to very bad thing to use, even though I've used them on many occasions without hiccups.

So if the GZL cable is LMR-240-ish then I'd be good with one booster for 60 meters of the Ecoflex cable. I guess if I join two cables to get the 60 meters with a BNC male-male the drop would be negligible?
Hey Miguel, I'm late to the party on this thread, but I'm curious about what actual cable lengths you are using. I noticed that you gave all specs in meters, but most of the replies from this side of the pond were in feet. Are you really running 60-100 meter antenna runs? 60m is 196', 100m is 328'. Both are really, really long cable runs.

This is an "old" thread regarding what I was trying to accomplish at the time I started it. But I'm currently up to 40m runs, because I didn't get the extra 20 from my boss, haha. So at the current state 40m. What I want is 60m due do cable paths and not getting physical structural shadows from 40m runs, LOS in other words. Even though 40m worked good last time with obstructions.

I don't think I've ever stated 60-100M in cable runs. 60M would be max. My only mention of 100m in this thread would be the specs of a cable.
