Few quetions about a choke....

It may help with an Imax 2K because of the antenna design itself. No guarantee it will help however. Also no guarantee you will need it.
Completely irrelevant as to the need for a choke at the feedpoint. Close neighbors can be affected by a perfect installation.
Again irrelevant. Front end overload is the more likely culprit when running an amp in close proximity to neighbors.
this is a good example for a rf choke. also id add the gpk to it in hoping it may decouple
the coax,.. make as pic shows DO NOT use barrel connectors deafects pupose imho
just use you rg213. as said earlier this ISNT a gureentee but i do feel its a good start
Why not use barrel connectors? How would they defeat the purpose? They are merely an extension of the coaxial cable itself.
Just seal 'em up good.
Exactly but you should do that wherever connectors of any type are used anyway.
i was assuming he was going to use smaller coax with a barrel connector
the form a choke using the small coax.if so wouldnt you be just choking off
the smaller coax while the larger coax would still radiate as if there was
no choke at all?? i never use barrel connectors for outdoors thats just me .
i assume if i lived in the dessert i would think otherwise...lol
A change in size of the feed line, or using a barrel connector, shouldn't make any difference as far as a choke being effective.
The only 'catch' with using a barrel connector outdoors is keeping the water out of it. There are a number of ways to do that weather proofing, pick the one you're familiar/comfortable with.

Yea, ive got away of keeping the barrel connector dry.....don't plan on tapeing it up....Im going to put me a ground rod out there too, so when it storms I can unhook it out there and hook it to the grd rod....
Well, since we are talking about the RF stuff, what would the chance be of going with a super penetrator 500, and a choke, the choke will be away from the mast pipe also....antenna will be up around 25-27ft, close to it....

You can put a choke on any coaxial feed line. How effective it is can be variable, may or may not do any good.
The idea is that a choke reduces/stops current on the outside of the coax fron radiating or getting back to the radio. Any feed line between the antenna and that choke can still radiate, so keeping that as short as possible is a good idea. The antenna's feed point is a good place to put that choke. No feed line to do any of that radiating, right?
Some times that's just not very practical, so get it as close as you can.
It also doesn't hurt to use more that one choke. One at the antenna and another where the feed line comes into the house?
