Question RG-11 vs RG-6

I have probably enough leftover RG-11 coax from a former project. Is it superior or inferior to RG-6?

I found one site that showed the dB loss at about 30% less with RG-11, which is higher (right?) on a non-log scale.

Is there another factor which makes the -6 superior?

Thanks for any input. Mike

Default Rg 6

I do not have the specifics, but I do know that RG6 has less signal loss than RG11. I think that it would also depend on how long your cable run would have to be (especially since you have RG11 already at hand).

Question dB loss/100' @ differing MHz

These are the numbers I got from a cable seller's site:

Cable gage 50 100 200 500 900 (MHz)
-------- ----- ----- ----- ------ ----- -----
RG-11U 14 1.00 1.50 2.20 3.7 5.20
RG---6U 18 1.46 2.05 2.83 --- 6.88

Am I messed up or is the loss higher with the -6?

That is backwards OITS, you are probably thinking of RG59. RG11 has a 14ga inner conductor whereas RG6 has a 18ga inner conductor, so the loss would be greater in the RG6. The loss for RG6 at 1gHz is about 6db per 100 feet and the loss for RG11 is about 4db per 100 feet at 1gHz. Assuming thet is pretty good quality RG11, I would use it.

Edit: if that is the specs for the cable you have, I would definately use it.

Default I think RG 11 is for transmitters - fat and stiff

Type: Center conductor: Cable diameter:
RG-59 20-23 gauge 0.242 inches
RG-6 18 gauge 0.265 inches
RG-11 14 gauge 0.405 inches

For 200+ foot runs on our antenna range we use Andrew FSJ4-75A Andrew Heliax.

For lessor runs we use RG-11.

RG-6 is only used for jumpers.

If you're only running 50-150', RG-6 is fine, but if you've got the RG-11 on hand, by all means use it.

hello,
I install cable for a living, and I can tell you that RG-11 is lower loss than RG-6. we use RG-11 for customer drops over 150ft because it is much lower loss. a word of wisdom, however: there is such a thing as TOO MANY db, and this will cause a basic analog TV picture to get lines and fuzz and a digital picture start tiling, and digital services like phone and internet will have strange issues, but yes, RG-11 is lower loss than RG-6, and could be used, depending on how well of a signal you are getting

Default I'm using mine

I have a piece I bought for my Channelmaster1160...turned out I measured wrong and came up 15' short from reaching my antenna!! LOL I also didn't realize when I bought it that you had to have a special fiting that would downsize the pin so it would actually fit into your equipment! So I got frustrated at the time and stored it. Although it's 8 years old, it's been in a dark, heated shed the whole time, so I'm sure it's as good as new. Putting the ends on with a crimper tool works alot better, doesn't it? I may just buy one used, do my crimping, and resell the thing on ebay.

This is classic! Use an RG6 jumper of 15' and install your preamplifier there.

I'm not trying to hijack this thread and since it is almost 3 years old I have a question about RG6 I just installed my new XG 91 with RG6 cable 100 ft of it but I didnt have a short piece to connect from antenna to preamp 7777 so I used a short piece of RG59...no signal was transferred however, so I assume I must use a short piece of RG6...am I correct?
I currently am straight from antenna to digital tuner via RG6 and I do have a signal coming through...just not amplified...

I don't think the RG59 is responsible for losing the signal altogether, per se. It may be a case where the inner conductor isn't big enough to fit properly into the spring fingers on the inside of the F spigot.

My guess is donny is right. Also make sure you are getting the DC voltage up to the 7777.

Hey Compudue, what crimper do you use for RG11/6 ? I've been using .429 and .324, respectively. The RG11 looks like it could benefit from more scrunching though.
