Hi All...I have two pieces of Cable TV hardline 3/4 in and both pieces are nearly 350-400 feetĀ 
long...one piece per customer please...here is the deal...the hardline has two high quality brass fittings/coax connectors on each end and I paid $60 a piece...they come with the hard line free...you will have to come down to Griffin and roll up your hardline...some is maybe 1 inch below the surface so a tiny amount of effort is required to get it on the surface...also a lot of the hardline is taped with electrical tape every 2 feet and that must be cut...you will need a few fresh rolls of electrical tape to tape the roll together as you roll it up. so first two callers who call me can have each a 350-400 ft run of 75 ohm 3/4 dia hardline with very low loss...you may ask how do I match to 50 ohms? there are two very easy methods...first is a frequency dependent matching line that would work if you use the hardline on a single band...second a 75 to 50 ohm balun is availabe from a number of sources that will allow the hardline to work on any and all ham bands..so my cell is 678-595-6235.
