[Antennas] VHF/UHF J-Poles Spacing and Feed Line

[kg6irh@ftnetwork.com]

I intend to build a 2 meter J-Pole, and a 70 cm J-Pole, withtin the next few weeks.
My plan is to mount them each on two inch plastic pipe and then mount them opposite them each other to a four inch vent pipe.

Will this be enough spacing if I were to be transmitting on both antennas at the same time?  Also, will this be enough spacing if I were NOT to be transmitting on both antenas at the same time?

I have about fifty foot run and intend to use RG-8X.  Would these be a sufficient feed line?

I have been licensed for less than a year and this is my first serious and permanent antenna project.  I made a twin-lead two meter J-Pole but this time intend to use 1/2" copper pipe. So any comments would be appreciated.
