Antenna Update

Moved the white UFO higher using a ten foot pole, reception has become more solid.
But we need a longer mounting pole, as am about 30.cm above the peak of the roof; three to five more feet would be ideal...

Would using a piece of straight electrical tubing be a good suggestion?
There is an electrical supply place near me that has them to 20 feet long.
Is this type of tubing strong enough?
