Does this antenna need to be tuned?

Yes. CB whips usually need the tip trimmed or the whip length adjusted to get SWR down, and you should check SWR with a meter before transmitting.

Will it work on a fiberglass roof or trunk?

A magnet mount needs a metal surface to hold and to act as a ground plane. On fiberglass or plastic you would need a metal plate under the magnet or a different mount.

Can I use it with a 10-meter ham radio?

It covers 26 to 30 MHz, which includes the 10-meter band, but SWR should be checked at your frequency before transmitting.

The antenna with its coil housing and 35-inch whip, the 3.5-inch magnet base with rubber boot, and 17 feet of RG58-A/U coax with a PL-259 connector.

Is 300 watts enough for an amplifier?

It handles up to 300 watts, so a small CB amplifier is fine. Higher-power setups should use an antenna rated above that.

Our take on the Tram Magnet-Mount CB Antenna Kit

The Tram Magnet-Mount CB Antenna Kit is a 35-inch stainless steel whip on a 3.5-inch magnetic base with a rubber boot, sold with 17 feet of RG58-A/U coax and a PL-259 connector. It covers 26 to 30 MHz and handles up to 300 watts, so it suits standard 40-channel CB radios and mild amplifier use. The magnet mount lets you move it between roof and trunk without drilling, which is the main appeal over fixed NMO or stud mounts. Owners of similar Tram kits report solid reception and easy setup, but the thin whip and magnet finish are the usual wear points on this class of antenna.

Pros

Magnet base with rubber boot protects paint
35-inch stainless whip is long enough for decent range on CB
17-foot coax gives room to route from trunk or roof to the radio
Handles up to 300 watts, so it tolerates a small amplifier
Installs and removes in seconds with no drilling

Cons

Magnet mount can shift or slide at highway speed in strong wind
Thin whip can bend or kink and is not replaceable on its own
Needs a ground plane, so it works better on metal roofs than on fiberglass
Coax and connector are fixed, so a damaged cable means a new kit
