I hear ya. I'm of the same opinion too. I don't have the energy to paste the (supposed) mathematics of the additional gain of 4 feet. Hell, there's even explanations for why 8 feet doesn't work as well under sea conditions (something about not staying more parallel to the water surface and how a shorter antenna maintains better conal angle).VHF is line of sight. You just lowered your antenna 4 feet. Figure it out. I always raise my 8 footers another 4 feet.
Understood.Its more than just how high it is, a 4 foot antenna has a 4db gain and 8 foot is 6db gain. You loose distance with lower gain.
So if you where to add a 4 foot extension it still would not match an 8 footer
I have two 8” digitals on my cabin and they work great

Yes, my Garmin MFDs are connected and communicating with each other, as well as the black box. I thought maybe it was a setting such as baud rate or AIS On, but those things all check out. Yes, there are terminating resistors. I'll keep at it as I obviously want the triangles on my bigger screens.Are you getting anything over the NMEA 2000 buss? Do you have terminating resistors at the ends of your network backbone?
When you're at rock bottom, definitely. To be fair, I've only gone offshore once, so hopefully the second trip will be much better.Only gets better from here.
