Chris Kb0wlf Superflex (FSJ-x) is not quite as good in an outdoor run, and may deteriorate quicker. At least that's what I've been told. FSJ-4 is still considered 1/2, but yes it does take different connectors.

Re: [Repeater-Builder] WANTED: heliax
Try this websitehttp://www.surpluscoax.com/ Little differnce in FSJ$ and LDF4 other then slight change in loss value and smaller min. bend radius for the FSJ. Big difference between LDF1 and FSJ4 size and loss figures. -- Doug N3DAB/WPRX486/WPJL709 Chris Curtis demo...@rollanet.org wrote: = Ok, so I also could use some heliax.

Re: [Repeater-Builder] WANTED: heliax
For heliax at 'make offer' prices, check the equipment for sale listings on the GNARC.org web page. This is good quality and some have connectors already mounted. Shipping will be a problem Good luck. It is good stuff especially for VHF and UHF 73 Curt W1FSM Chris Curtis wrote: Ok, so I also could use some heliax.

RE: [Repeater-Builder] WANTED: heliax
I appreciate the tips on where to find the stuff. Does anyone have an opinion of installing the FSJ product instead of the LDF product? Remember, my budget gives me 2 options at the moment. LDF1 1/4 inch OR the cheap on ebay FSJ4 1/2 inch. That's the crux, is flexi BAD for a run from the antenna to the shack? Both connection points are weather proof.

RE: [Repeater-Builder] WANTED: heliax
I really don't like using Superflex (FSJ) outdoors. The jacket on FSJ is much thinner than it is on LDF, making it easier to get water in due to a small nick. Also, the corrugation on FSJ is helical (spiral), whereas LDF is annular (rings). The helical corrugation also makes it easier for water to spiral down the line in the vent you get a knick in it somewhere along the vertical run. Granted, the effects of water trapped between jacket and shield isn't a huge problem; it's when the water gets forced into the connector body and ends up flooding the contact interface that you really have a problem... If you want the installation to last, hold out for LDF. You might find 7/8 cheaper on the surplus market than 1/2 because it's more commonly used, especially in longer lengths. --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Chris Curtis Sent: Tuesday, February 24, 2009 5:13 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] WANTED: heliax I appreciate the tips on where to find the stuff.

RE: [Repeater-Builder] WANTED: heliax
Chris, I'd use LDF for the long run, and FSJ for jumpers. Also, you'll need a short jumper of RG-213, 9914, or similar at the antenna end to allow you to rotate the beam(s). I don't think the FSJ is meant to be *THAT* flexible. FWIW - I run 1/2 Heliax to my 2m/70cm stick at the top of my tower, with a short section of 9914 from the Heliax to the antenna itself. Inside the shack, I use FSJ1-50 (I think that's the nomenclature - it's 1/4, RG-58 diameter) as jumpers to the rigs - no more than 3' in length.

RE: [Repeater-Builder] WANTED: heliax
Thanks! I neglected to mention that the 70cm beam would be fixed rather than rotatable. Guess, I'll do the ldf outside and fsj or 214 inside.

Re: [Repeater-Builder] WANTED: heliax
I posed this question to Tessco a few years ago regarding the use of FSJ cable outdoors. Evidently there were concerns years ago regarding the use of FSJ, or Superflex cables for antenna jumpers. I was assured that any past problems have been resolved. I never verified this with the manufacturer. 73, Joe, K1ike Chris Curtis wrote: Now, I understand fsj is the flexi but is it really that bad to install from antenna to shack?
RE: [Repeater-Builder] WANTED: heliax
You want the 1/2 FSJ for minimum loss in the line. the 1/4 cable will have about twice as much loss. With Heliax cable larger is better, up to what your pocket book can handle. -- Doug N3DAB/WPRX486/WPJL709 Chris Curtis demo...@rollanet.org wrote: = I appreciate the tips on where to find the stuff.
