    2.4 GHz Antenna Routing

    I have been on this forum for awhile, learning as much as I can, but this is my first post. I am in the process of putting together a Victoria class submarine 3D printed from the files Bob sells on the website. I have purchased the 70mm R&R WTC, and had Bob install a forward servo.

    My question relates to receiver placement and routing of the 2.4 GHz antenna coax. I have an FrSky X18, and a TD R10 receiver. I purchased the 2.4 GHz antenna extension kit from Bob as well. The receiver will only fit in the battery compartment. However, this raises the question of where to route the antenna. If I have it penetrate the forward endcap, then it is easy to route, but causes issues with disassembly of the WTC for post mission and maintenance since the core of the cylinder is attached to the aft endcap. Routing the antenna through the center tube to the aft endcap, I would imagine will cause issues in that it is parallel and in close proximity with the power and servo wires (unless the shielding does a better job than I am expecting). I have seen low frequency radio antennas routed on the outside of the ballast tank, by notching the ballast tank bulkheads, but those antennas were smaller in diameter. Also, not sure if the antenna extension is long enough to reach the aft endcap, forward again sufficiently to reach the top of the sail hidden as a mast or periscope.

    I apologize if I have missed posts related to this specific question. I would appreciate any insight.

    Thank you.

    The antenna extension should be plenty long enough to get down the central wire conduit and out the back of the boat. Your interference concern is valid, however. Both power and servo wires will be sharing a very enclosed space. The coax portion of a 2.4 GHz receiver antenna does a good job of shielding the signal conductor from nearby electrical noise. It is generally not very vulnerable to interference from your power wires and servo leads.

      This was s good question - thank you for posting Tony. Bob - do you have photos of how your tandem antenna and receiver are installed in an R&R cylinder? That would be very helpful. Thank you.

        Bob,

        Thank you for the information. I am glad to know that this is a viable way to route the antenna to make maintenance easier on the cylinder.

          No, I don't. I don't think I've done an R&R with a tandem antenna install yet.
