The middle ground is where I (we) all want to be. It's fairly clear, from the previous experienced posts, that the signal quality is directly proportional to your location. Even with satellite equipment....
There are lots of pro's and con's.
If you want to use a satellite system. It needs to be set up at the end of the cruising day.
Using a directional aerial needs to be raised and directed, at the end of the cruising day.
Is an omni-directional aerial a plausible solution to the end of the day set-up regime?
Looking at the pictures on the Ely Chandlery site, the external fittings appear to be designed for sidewall not roof fitting. Is this what everybody who has one does or has anyone found a way of putting them on the roof? Anybody got pics?
I used 3/4 inch scoop fittings (obviously downward facing)to terminate the intake & exhaust on the outside of my cabin sides. £10 for two on Ebay. I didn't see the need for roof fittings.
They're certainly as good as any other shower pump I've seen.
Though I think all the boats I've been on have had 'hip bath' style showers which are actually quite deep, so if the pump doesn't quite keep up it doesn't matter. I'm not sure I'd want something reliant on a pump with only 1/2" of space before the floor takes a soaking!
I'm just experimenting with a bilge pump, plastic food box with clip down lid and a float switch with auto 12v relay. My theory is that as a bilge pump takes in all sorts of gunk, it will be able to pump out the shower waste with relative ease. The float switch allows automatic switching on and off. It's in and connected up, but haven't properly tested it yet as the shower needs sealing before it's used. It cost me about £20.
