just woundering what coax people are runnning, as i just bought myself a 25 mhz to 1300ghz antenna and i'm going to mount it on the roof and looking for the best type of cable to run with low loss. for testing puposes i have been using a 1 metre length of 75 ohm tv coax.

If its for recieve and only over a short distance I would just go with RG58 it's when you get into transmitting and over a long distance between the antenna and radio you would need better coax

yes Shane is correct, you can get RG58U from Jaycar, Dick Smith now only sell RG59U which is 75Ohm cable it is rather cheap at Jaycar and they also have alot of connectors in stock from BNC through to N Type

What you need is a good quality 50 ohm coax. As you are going to the expense to put an outside antenna, you will be wasting your time and money with RG58 coax. Get LMR-195 for short runs ( 5m ) and LMR-400 for longer runs. You will notice the difference in the higher frequencies. Both these coaxes are used in the WIFI antenna installations and can be found at all good 2.4 Gig comms shops. If you have any problems in locating the coax, there is a place here on the Gold Coast that will make up custom coax leads with what ever coax connectors you want on them.

I use LMR-400 for base installations providing cable run is no more than 22-25 metres over that LMR-600. For vehicles I use LMR-240.
People don't realise how much power and received signal can be lost in relatively short lossy feedlines such as RG58.
A typical uhf cb installation with 5 metres of RG58 for example 5 watts in will see about 3 watts delivered to the antenna add to this lossy pl259's and you are down to losing nearly half the power transmitted from the radio.
