A quick question

On the radio link receiver there is a rubber fuse type thing on the antenna its a pain because i want to feed whole antenna wire through a small hole in the hull,,, can i remove iti am using it in a carbon fibre hull so with my other receiver (s) i just fed the whole antenna through the port where steering line goes
is this rubber thing standard on all their receivers?
and no i dont want to drill a bigger hole in the hull

The AT9 package is ok (apart from transmitter screen which is impossible to read in bright sunlight)well it s cheap in thailand it has far more channels than i would ever need i do not use any telemetry but sail in ocean so strong signal is paramount

any advice would be welcome

A quick answer (well, two answers actually):

No, it's not a fuse and no, you can't remove it without seriously compromising the range. Sorry if that's not what you wanted to hear.

The only part that needs to be outside the hull is the shiny 1" at the end because that is the aerial.  The rest is a shielded coax feed for it.  The length of both is quite critical for performance.

Thank you both
unfortunately due to this rubber thing  i can only get about a quarter of an inch of the aerial (if that)outside the boat Grrrr
signal seems ok but it does twitch occasionally whereas my other receivers i never had a problem with

I think you'll need to re-site the receiver. The manual for the Rx says that the aerial should be kept at least 1/2" (12mm) away from any metal or carbon-fibre skin etc.

As unhappy as you are about increasing the hole size, doing that and using a grommet is the "proper" approved way of getting a wire through a panel.  It serves to both seal against water getting in that way and to protect the wire against chafing on the edges of the hole.  I have a tendency to use a clear waterproof adhesive like UHU All-purpose to do the job.
In all probability, the "rubber fuse" is likely to be the outer sleeve of the coax folded back over itself to provide a firm watertight or vibration resistant seal in the right size hole.

Thanks again guys re siting is not an option as whole hull is carbon fibre its a stockmaritime 3x1 hull


i might sail until the really  windy season with this and in the meantime try to locate another transmitter that i had before (storm I6s) its made by the OEM of the orange T6 and its receiver has 2 long wires i just feed through the steering lines.
its a shame i had phenomenal range before! just the transmitter got old and corroded (i stand in the sea off a beach its 35 degrees plus each day so sweat and sea water don't help)so no transmitter lasts more than a few years.
i never checked that the antenna was different with this receiver so its my fault


Also the receiver is situated right between the servos on top of the battery so i suppose it gets a fair bit of interference although it never seemed to bother the cheap charlie system before
At the moment (today) i only get a bit of problems when the boat is healing away from me at a distance of i suppose 100 metres so its not a massive issue until we start getting the big waves and swell which i sure will interfere more.
