Hi Carlos,

I'd recommend RG-8X.  About the same size as RG-58 (which should be
avoided), but much better made.

Attenuation @ 100ft/Pwr/Efficiency
0.9dB @ 10MHz/2.16kW/80% E
1.4dB @ 30MHz/1.24kW/69% E
2.1dB @ 50MHz/.96kW/62% E
3.6dB @ 150MHz/0.55kW/43.5% E
6.3dB @ 450MHz/0.31kW/23.2% E\

Also, while doing your shopping, HRO and DX engineering are good, but A.J.
at JefaTech (http://www.jefatech.com/) is local, a fellow ham, and a nice
guy who has done really good things for the club.  He's got every type of
coax you would ever need and can cut to your specific length and terminate
with your connectors of choice.

When I bought the Buddipole I got 25ft of coax as part of the kit. Of course
I need more. Looking at coax loss tables I almost went for LMR-400 until I
saw how rigid it is. Since I'm doing QRP I'm looking for low loss but since
I'm also mobile, well, you get the picture.

I was looking at some options from DXengineering : DXE-8U low loss cable
seems like a good choice.  Any recommendations on what type of coax to get?

Carlos
