So,,, I just read several pages of the DSM thread where everyone says the diversity receivers need to be positioned with the label facing up for the internal antenna to be effective....
And here are pictures of receivers velcroed upside-down???
Man,,,, FM 1024 PCM radios were never this picky...Still not sold on all this DSM stuff,,,
I really think that DSM is more of a convenience thing to people that no longer wanted to deal with multiple channels any longer..
Its not necessarily a better radio...
Grim,
You did. Lol. You got everyone scared to death they are doing everything wrong.
On and on about label facing up. I didn't read it though, It was straight from the horses mouth in the Diversity receiver video you made. Guessing you wrote it somewhere too if Frank read it.
Just more BS is all. Same as long antenna's being any kind of a requirement whatsoever.
The internal antenna is polarized the same way up or down. Having a circuit board over top of the internal antenna is mostly irrelevant unless you are in flying over the lake with your transmitter controlling your boat from above. Not sure the difference from shoreline is enough to matter. Possibly a iota but unlikely much at all if any different. I like mine under the lid. Where else you going to put it to face it up. On the bottom. That is worse down in the boat. Over a servo. I mean really where is it highest in the box and out of possible water intrusion and convenient to get to. I will always choose under the lid upside down so all the antenna is going up the tube and that is perfectly fine for almost every installation there has ever been.
I love the Futaba 2.4ghz and never have had a single issue with it using it as purchased well except the internal thin tin foil antennas corroding in the receivers. Straight up junk that doesn't even belong in a potentially damp environment our receivers sometimes get subjected to. The surface receivers would be worlds ahead if they just dumped that internal tin foil pos antenna and used two wires like their aircraft receivers utilize. Even if one was left in the box it would be WAY better design that would increase the range considerably.
Why do you think they don't build the aircraft receivers the same way ? To maximize the range is my guess out of necessity. Two wire antennas.
Please post printed material from Futaba that states a recommendation of this long antenna being installed for marine use and the label must be facing up. It is like a act of god to even find the long antennas so pretty sure they aren't expecting you to use them exclusively for marine duty or they would be available with it either already on the receivers. or separately or a place to send them to get it done and what it cost to do. I do not see any of that ANYWHERE !!!!
Futaba Team Marine is surely not authorized from corporate Futaba to make these recommendations to do so on their behalf.
They are advertised for marine use but none of this is in any literature from Futaba I don't believe so has me thinking it may just be more BS coming from mostly a single individual on a mission to get people to do what he does because he thinks it is required for some reason. Of coure no arguement the antenna need to be up a tube as high as te litgtle short one will reach and all of it up the tube. If that is not possible MAYBE you could benefit from a long one but to just say if your using it in a boat it must be replaced to be dependable is completely incorrect.
I have never used a long antenna yet and have never had a need to and I build a lot of top level high end race boats that have won at the top level of racing at the Winternationals and the Superboat shootout on numerous occassions.
Sure if you can't get your antenna up out of the boat then maybe you don't need a long antenna as much as taught how to install it so the antenna they come with is plenty. I actually despise those long pos with a vengeance. People tear up the short ones imagine another foot of wire in the box. OMG. NO!!!!!!
You give someone that much wire and they are running through the sides of the box and remote mounting the tube and all sorts of scary chit no body should be given enough wire to even do.
Just do not ever fold the coax over the top of tube and cap it. That is sure death to the fragile coax cable.
