Helix Designs RX-491 antenna cover
Coming from Helix Designs are two new antenna mounts for the use with the Sanwa RX-491 receiver. The 3-D-printed parts offer a clean sleek way to hold and protect the receiver’s antenna. Helix are offering two different versions; Low Profile and Long Range. The low profile cover keeps the antenna in a small space low and out of the way for a clean looking electronics install. Recommended for medium to small track sizes. Long range holds the antenna upright for a small compact way to make the most range and consistency possible. This comes with the set screw and perfect length antenna tube for the Sanwa RX-491. The latter mount is recommended for the largest of tracks out there. Installation of both required the use of optional double sided tape.
