does a detached over-the-air television antenna help?

Our trailer has the new type of roof television antenna...stays in place, as opposed to the older 'crank it up and down / turn it to point toward wherever signal is best' type

Even with that, sometimes beyond signal range for over-the-air broadcast channels

Came across a tripod-mounted flying-saucer shaped antenna described as: KING OmniGo Portable Omnidirectional Over-The-Air HDTV Antenna, Black...it would sit on the ground, and connect through the 'cable in' outlet on the outside of the trailer

Would this be any better at picking up signals that the factory roof-mounted antenna we already have does?

(not interested in a satellite solution...we're occasional weekenders, and our trailer isn't the type for long-term television watching)

Not any better sitting on tripod. Elevated may help

Height is usually helpful. The King would be lower than what you have IMO. And you must set it up and take it down.
