LMR-600 is 50 ohm and can not be used. RG-11 is quite a bit thicker than RG-6. RG-6 will work fine.

You don't know what you're talking about.

Mike-s, YOU don't know what YOU are talking about.

LMR-600 SPECS states that it IS 50 ohm (FIFTY OHM) coax.

So what? You claimed it "can not be used", which is completely and utterly false. Get a clue.

I need 200' of coax for SWM at my daughters. As a test I hooked up 304' of various RG6 coax lengths in the Phoenix area where the DTV sat signals are 90+. None of this coax had SWM quality connectors or barrel connectors. In 4 weeks the HR44 receiver hung twice.

Questions: With better RG6 connectors and solid copper core what are my chances of good reception in the Seattle area with RG6? Should I get say 2x 100' lengths of coax?

Both the Portland and Seattle spot beam maps show a strong signal in the Seattle area.

My open face Dish 1000.4 dish with a triple LNB works fine with 250' (5-50' lengths) of RG6, but it doesn't need to power an automatic dish internals, just the LNB and Solo Node.

I watched a Directv training video years ago when SWM first came out.
It explained the big advantage of SWM was that it could usually be installed on existing RG59 houses and rewiring should be kept to a minimum.
For what it’s worth.

I bought the quad shield stuff because I needed new cable and it looked worth the extra money.

No so, RG 59 will not work with most Dish systems, we also had issue when using it at
Home with cable service. Somewhat like saying 14 gauge wire will work for a 20 amp circuit.

In a pinch, RG-59 "could" be used for extremely short distance, say 10-20ft for testing purposes. Its' loss per ft is considerably higher and typically very cheaply made (60% braided shielding) making it an extremely POOR CHOICE and IS NOT RECOMMENDED BY ANY SATELLITE PROVIDERS.

Even the bottom of the barrel version RG-6 which has SINGLE LAYER OF FOIL for 100% shielding coverage IS a FAR BETTER CHOICE than RG59..

However, folks do need to understand that QUAD shielded RG-6 IS NOT NECESSARY for Satellite installations. Because of the extra shielding layers it does have MORE loss than standard SINGLE Foil shielding since the outside dimension is the same as single shielded the CENTER WIRE MUST BE SMALLER in order to accommodate the extra shielding..

Yep, there IS two different RG-6 fittings, one for single shield and one for Quad shield.

Mike-s, YOU don't know what YOU are talking about.

LMR-600 SPECS states that it IS 50 ohm (FIFTY OHM) coax.

RG-11 IS BIGGER than RG-6 AND RG-6 should be FINE for Satellite LNB runs up to at least 100 ft.

Granted, RG11 does have much less loss than RG-6 so in some respect and depending on how good of view your dish has might work a bit better if you have some trees infringing on your view or terrestrial point to point microwave relays close to your dish path..

I used to work for a "C" band (big dish) installer many years ago, often ran about 100 to 150 ft of dual RG-6 swept tested for Sat installs.. Never had any issue getting it to work.

Only a couple of times we needed to use RG-11, had a couple of installs that were 200-250 ft, to get a good view of the southern sky..

By the way, last time we used LMR-600 would have been for the first gen C band dish when they used a separate LNA and down converter. LNA mounted on the feedhorn, ran 8ft of LMR-600 through the feed horn hook to the back of the dish then mounted the down converter there..

And YES, the LNA output was 50 ohm, and the down converter input was 50 ohm, so you used 50ohm coax for that connection.. From the block converter AND more modern LNB the output IS 75 OHM...

For Dish or Direct mini dish systems the LNB output IS 75 OHM and the receiver block input IS 75 OHM..

Using 50 OHM coax is not going to kill things but will present an impedance mismatch which may drastically reduce the performance of the receiver.. Basically counter productive.

What part of my response are you referring to? LMR-600 is 50 ohm, RG-11 is thicker, or RG-6 will work fine.

No line loss. It has weatherproof Belden connectors to limit interference from the weather, nickel and anti-corrosion materials, UL listed, 14 AWG solid copper core @ 3Gigahertz, 75 ohm.

I have been having problems with my satellite setup, and this is the last thing to replace. We camp in a lot of places where we need 100' to get to a place with a clear view. Hoping this helps solve my issues. And also hoping to never buy another cable! I was just wondering if anybody else has used this cable. Thanks for the replies!
