Add on a 30" or even a 48" length of pole to your current pole that you already have. 
 
For example, if you have a 30" pole already, adding a 30" pole link will effectively provide you with 60" inches of reach.  And again, if you have a 48" pole, and you add on a 30" pole link then you will have 78" inches of effective length; and once more, if you have a 48" pole and you add another 48" pole link, you will then have a 96" long pole length.
