RE: [Repeater-Builder] Re: Andrew Heliax LDF1-50
I think we may be playing cross-questions and crooked answers here... After referencing Catalog 38, you are correct regarding FSJ. I won't even go into the VXL series cable...

Re: [Repeater-Builder] Re: Andrew Heliax LDF1-50
Are you sure it was LDF1 and not FSJ1? LDF1 is VERY rare (I've never seen it), but FSJ1 is pretty common.

Yup, Real LDF series with soft foam and everything. On Apr 8, 2005 12:05 PM, Jim B. [EMAIL PROTECTED] wrote: Are you sure it was LDF1 and not FSJ1?

Superflex has a finer corrugation to allow it to bend easier, and with a tighter radius. But of course, if it said LDF, then it's LDF...heh. On Apr 8, 2005 12:05 PM, Jim B.

Re: [Repeater-Builder] Re: Andrew Heliax LDF1-50
I just looked at it, and yeah it is LDF1-50A. The reducers I had were too small for it, I was debating drilling out the one for RG-8X but then that would leave none of the reducer.

Re: [Repeater-Builder] Re: Andrew Heliax LDF1-50
I can't see why you can't use it, even with the PL-259 connectors. My concern was that it is very small in diameter and may suffer damage easily on very long exposed runs.

On a related note, I am in the market for a VHF circulator with 3 connectors (Not 2 and a built in dummy load) preferably SO-239 but I will consider N if it can be opened so the connectors can be changed.
