YT Telescopic Mast Range
A little stronger than the PT Series masts for any particular height. Compact enough to often allow vehicle installation in a vertical position. The need to transport the mast in the horizontal position on the roof of the vehicle, as is necessary with most WT masts, is therefore often avoided. The YT Series often fits where other series are too weak or too long when retracted.
The volume of the YT Series makes extension with a handpump an acceptable method which offers simplicity.

If one compares this YT9 mast protrusion above the roof of the vehicle with that on a previous page, one can see the advantageous compactness of the short YT Series.
