K&S KS5761 antenna tube with orange holders D=3.5MM L=60CM  [KS5761]

Antenna tube for RC radio routing

The K&S KS5761 antenna tube is an RC-scale replacement part designed to route and protect radio antenna leads inside scale models. It uses a 3.5mm internal diameter to accept common antenna inserts and comes with orange snap-in holders that secure the tube in place on chassis or body panels.

Compatibility is intentionally generic: the tube serves as a universal guide for 3.5mm antenna fittings used across many model car and truck builds. Because this is an accessory for scale models, verify fit against your existing antenna insert diameter before installation.

Installation is straightforward: cut the tube to the needed length, slide the antenna through, and locate the orange holders where the tube passes through the body or a bulkhead. The holders snap into place to keep the tube aligned and reduce unwanted movement during driving or servicing.

In tuning and setup the tube helps keep the antenna routing consistent and reduces stress at the antenna feed point, which can lower the chance of signal disruption caused by pinched or kinked leads. It is intended as a simple maintenance and tidy-up part rather than an electrical component.
