Hey Shane, Pay attention much? Do you even know what POTA is?
There are no POTA stations running 5 over 5 stacks on portable 150 foot towers in the park.
Huh?? How about the park hunters, working all of us at the parks?
Although I suspect most are using a tribander at 35 ft and not a stack on 150 ft tower :-)

Don't know, but I just got off the air (14.237) with CE3WB in Santiago, Chili. He uses a rotatable dipole.
And he was working you while you were at a park??


100 watts and an Endfedz EF-20 on my end.
OK, I know this topic has wandered, but it recently was about the antenna(s) that home stations use to work weak portables in the field, like at POTA listed parks.
So you worked a guy in Chile with a rotatable dipole, and you used an Endfedz EF-20. Were EITHER of you portable at a park 
?
Get on the air more and listen. All the Western VE parks were on the air last night
talking to France and England. Ten meters was open to Japan last night. Here's the deal, just like Real Estate it is location, location, location.
If you are 100 feet above see level and have your 150 foot tower you are 250 feet total. If you're at 580 feet above sea level with a wire 20 feet in the air your antenna is at 600 feet. It's like me being at your location with a 500 foot tower.
Unless you're in Florida, most parks have high elevation. Set up on an overlook you don't need much. One of the POTA stations last night made a Contact almost 1500 miles and the other station was running only 5 watts!!!
