Customer Reviews

Good product
Installs easily to mirror bracket, even thicker pod mirror types. Also includes hardware to mount to 'wings' using a clamping piece with rubber feet. It appears that it would also work with any standard CB antenna bracket, though I haven't tried it.

Replaceable wire is a step up from the magnetic pucks, where you have to replace the entire unit if the wire is damaged. Easier to install when the wire is separate. The included wire is also more substantial than the super thin wires on the magnetic antenna.

Smaller magnetic antenna on the roof can have dropouts due to a 'sundial' effect when you are driving in certain directions, this moves the antenna away from the truck so you get an uninterrupted view of the satellite.

I broke my original magnetic roof mount by accident, not enough slack in the wire opening the door. Replaced with the low-profile unit which started going bad after ~6 months. Having both installed and being able to swap antenna plugs at the radio unit with the signal strength indicator showing, the difference was significant, 6/10 bars on low profile and 10/10 with truck antenna. Terrestrial repeater reception was also much improved.

Highly recommended.

Sirius RadioTruck Antenna
My truck has a fiberglass roof and a large air dam that blocked the signal and with the fiberglass roof it made mounting the other antenna difficult. With the hockey puck style antenna my reception was fair at best and never went above 2 bars on the radio. With this antenna it rarely goes below three bars of signal strength (full signal) It was easy to mount & well constructed. I would recommend it highly

Great Home Antenna
I purchased this Sirius antenna to mount outside on my house. It provides much better reception (no signal drop-out) than the small "hockey-puck" antennas. The mounting bracket and hardware made attachment along the roof-line easy. Its profile (on a short mast) keeps it above the roof and free from being covered with snow. I wish the cable was about 5 feet longer, but extension cables can be acquired. A great performing antenna for home, truck, or RV.
