With that I should go on to say.. the proper install of those components is important too.
To take full advantage of a diversity receiver you have to have it installed properly too. The label NEEDS to face up in the radio box for best results.
Then.. on to the antenna.. as vertical as you can make it.. and as far from the water as you cam make it is best.
The TX antenna must also be as vertical as you can make it.

I’d like to see the install, I’d be surprised if the problem was the antenna, more likely it was to close to a conductor or some other issue, like weak or bad battery or switch. Over the years I’ve observed many issues blamed on the radio when in fact it was something that the modeler did or didn’t do during the maintenance or installation. Just my 2 cents.You might want to have another look at that, especially with your twin.
I know of one very experienced racer (Futaba sponsored) that had his 60 hydro go into the bank.
Again, Futaba is recommending the long antenna.
Some with twins like mine have had issues but I think possibly the antenna wire might have slid down inside the tube which would have put the tip closer than 2 inches. I have mine secured so the
That’s a recent change, seems like if it’s important they would have them available, probably for free, and FCC would probably want them installed by a “professional”

John, That recommendation .. comes from the marine team... yes.. not making excuses for Futaba USA. But it is the TEAM that the recommendation is coming from.
As a Futaba user and in all the testing I have done (on my own.. my time.... my dime.. ) this is what came from the testing. We have seen issues on the water when not following this.. so it is BEST.. (you have to determine if this is a fit for you) to consider the teams recommendation.
Some take that recommendation and some will not.. some will have issues and some will not..
Not sure how to word this.. its a tough nut......
Thank you

Thanks Mike,
I know, I can also read between the lines. I’ve run only Futaba in boats and car since the 70’s with never an issue. I have a stash of the longer antennas but haven’t made the change yet. If it ain’t broke don’t fix it. I haven’t had a single symptom in any of my boats.
Mike we’re slowly getting settled after our move, maybe done in another 5 years! I will get to the HO Shay soon if you are still interested. Do you know anyone interested in the Big Boy?
Thanks John

I think there is some confusion about the length of the wire, only the last 1.125" is the antenna the rest is coax cable ( do the math, 1/4 wave at 2.4 ghz is 1.125" ) and yes it is a good idea to get the antenna in the clear, the "lump" on the end of the FlySky antenna is a brass tube 1.125" long soldered to the braid of the coax making it a dipole witch has more gain than just the stub antenna, and yes the dipole is directional in the horizontal position and unidirectional in the vertical position

Terry,
I ordered two of the Futaba antennas from Gizmo. I received two damaged pieces because they were shipped in a Priority Mail Flat Rate Envelope without any protection or padding. The tear through the side of the envelope damaged both plastic bags & both antennas. What are they thinking about for a cost of $38.05?

Jim,
I think the shipper did not pack it safely. It looks like
it was tore up in one of their processing machines. When
Packed properly that usually doesn’t happen. I ship over
500 packages a year and have no problem with USPS service.
USPS moves a lot of mail for a Very Reasonable price.
UPS and Fed Ex are way more pricey. One example for UPS:
I had to ship two 57 mm propellers to Washington State on Labor
Day weekend and they wanted $90.00 what a crime. The padded
Box will come much better I would believe.
Good Luck Testing,
Mark Sholund

Sounds like something that happened to me years ago. I had ordered a hard drive shaft from Dumas(before I knew better) and, for some unknown reason, it took forever to arrive. When it did, the driver(it was sent UPS) had me sign for it, verifying the package was undamaged. After I signed for the package, he informed me that it was the second or third one sent. Apparently, the first one was literally bent in half and, being a model boater himself, he didn't deliver it due to being damaged. If there was a second, he didn't know why it wasn't delivered, just that he was instructed to have me sign for receipt for the one I did get.
