So you used the remaining pvc piece( on the right, bottom picture) with the hex on it & used Flex Seal & caulked around it to water proof it, if I’m understanding correctly.
Did you do anything underneath?
More Flex Seal, etc.
I just bought one of these & will do this before I put it up in the air to eliminate any problems,
Thanks for the info & clarification of questions I’ve asked.

- I've always wondered how well a 3/4 \λ/ave GP would help get a signal up and out of a steep valley. If you removed the matching network from the Penetrator and ran it direct-drive as in a short wire direct from the bottom insulator bolt to the base of the radiator and extended it out to about 26.9 feet - including the 8" - 10" top hat rods - it would provide considerable gain (~6dB) over the Starduster but at a higher angle.
Perhaps too high if you're not down in a real hole - however, if you are then you might see gain over the Starduster.
I've tried everything to get my new spt-500 swr set and nothing has worked, swr at 11 meters is 3.5 - 4.0, 10 meters is 2.5 - 3.5. None of the suggested lengths list here or on any other forums has worked for me so far, what am I missing?
The pic of 19' is for 10 or 12 meter so I would go 22' 9" for starters for 11 meter and you can't check your swr when the antenna is close to the ground that is why I made a tip over mass mount because you might have to raise & lower it several times to adjust it and check it where it will finally rest. And first of all make sure your matching device is assembled correctly. You only adjust the top tubing assembly to get your final length with all other tubing joints overlapping 2 or 3 inchs.
