_______________________________________________Hi
If you want to go “cheap” use coax intended for satellite TV reception. Be carefull about 75ohm, as the Hack RF is a 50 ohm system, you can use RG58U not to costly, don’t expect good performance above 1.2 GHz. Not sure what you want to intercept, if it VHF UHF you will be ok, else you could try RG213 but that ½ inch thich and you will have to adapt.
The thinner coax RG179 /178 will be fairly lossy.
I suggest personaly start with RG58 its cost effective and maybe an LNA near the antenna

Coax loss can be a big issue.
Given the low power levels you will suffer less loss on a long run using 75 ohm coax cable which is designed for low loss, even assuming you do nothing about the mismatch at the ends of the run. All that is good up to about 1ghz where more specialized coax is needed for minimum loss.
The antenna is a significant part of the equation and you are well advised to use an antenna suited for the frequency of interest. Broadband antennas like discones have very low gain, and they pull in other strong signals you don't want.

I have a HackrfOne with an Ant500 antenna connected to my workstation in my basement (where the internet connection lives). I need to move the antenna out of the basement to improve reception, so I thought I would use coax to connect the antenna from upstairs to the HackrfOne.
I'm too new to SDR to be confident about just moving the antenna and using a spare length of cable coax. Please provide some help on selecting, sizing and connecting coax between the HackrfOne and the Ant500.
Thanks
