RG6 vs RG59 - How Your Coaxial Cable Impacts Your TV Reception

hey YouTube it's Tyra the antenna man in

this video I'm going to demonstrate the

differences between our g6 and rg59 coax

cable I'm going to be using these three

cables this is an rg59 cable this is an

RG 6 tool shield cable and this is an

rg6 quad shield cable I feel that too

many people believe that there's only

one kind of coaxial cable out there or

they don't even think about the coaxial

cable but let me tell you the coaxial

cable that you use has a huge impact on

how reliable your reception is if you

use an antenna for TV this white cable

is a cheap rg59 coax okay below that

commonly comes with junk antenna models

I'd tell people not to buy but they buy

them anyway this is an example of one

this is an example of one and this is an

example of one a lot of times people buy

these antennas thinking that they'll

save money compared to buying a better

more robust model and on top of not

having a good antenna they have a junk

cable that pretty much kills their

signal rg59 cable isn't shielded as well

as rg6 but a lot of times the center

conductor is made of copper clad steel

instead of solid copper copper clad

steel doesn't conduct as well as solid

copper there's more prone to signal loss

this can also cause problems if you're

using a preamp or the antenna has a

preamp built into it the copper clad

steel simply cannot carry the voltage

needed to power the preamp up at the

antenna these two cables are RG 6 cables

this one here is an RG 6 dual shield

cable it's insulated a lot better than

the rg59 cable and uses solid copper as

a center conductor this is an rg6 quad

shield cable so it's insulate a little

bit better than the dual shield cable

but overall both of these are much

better than the rg59 cable you can

better see the size of the Center

conductors and shielding with this

picture taken from the side when the

cables are prepped for compression

fittings you'll note that there's very

little shielding in the generic rg59

cable while the rg6 dual shield cable

has a decent amount of shielding to

the center conductor from signal Lawson

interference and the rg6 quad shield

cable on the right has even more

shielding than the rg6 dual shield cable

in the middle I'm now going to

demonstrate how well each of these

coaxial cables work when connected from

an antenna to a TV set I'm using the

same antenna in the same exact location

for each of these cables and each cable

is cut to exactly 25 feet so you're

going to see how much of an impact the

cable you use has on your TV reception

here's a signal on a TV station with a

thick rg6 quad shield cable I'm getting

about a 66 to 70 percent signal which is

very good and would likely hold up well

in bad weather conditions when I

switched the rg6 dual shield cable the

signal drops about 5 percent which could

have an impact on the reception of a

certain station depending on how weak

the signal is when I connect the cheap

rg59 cable the signal drops down

significantly to around 53 to 56 percent

which would definitely be more

problematic in bad weather compared to

the nearly 70 percent signal that I had

with the rg6 quad shield cable most of

you can clearly see the difference

between these three cables and the

signal loss but some of you may say what

does it matter if I get a 70 percent

signal or a 55 percent signal I still

get a solid crystal-clear picture

well as it turns out I gave these cables

the benefit of the doubt because the

tuner I use that shows the percentages

on the TV set there's a very good job

decoding weaker TV stations the TV set

itself does not do a good job hence why

I use that tuner not only to demonstrate

the signal percentages for you guys but

to watch TV on my own time

so I'm going to test out these cables

now on the tuner behind me to show you

the difference with these cables if

you've had a TV set that doesn't have a

good tuner that may have problems

decoding weaker TV stations this is a

topic I talked about in a prior video

but I'll refresh it just for those of

you that are not aware some TV sets do a

better job decoding weaker stations than

others so I'm going to test out these

cables on a TV set that I know doesn't

do a good job with weaker stations to

show you the situation you

be in with the rg6 quad shield cable

connected I get a solid signal on my

older panasonic plasma TV no breakup

whatsoever when I switched to the RG 6

dual shield cable there is a little bit

of breakup here and there but nothing

too major however when I use the rg59

cable the TV station is a jumbled mess

of pixels and completely unwatchable if

you have a TV station that's a jumbled

mess of pixels replacing your cable can

make a huge difference you can clearly

see the difference between using a

quality rg6 quad shield cable and using

a junk cable that came with the cheap

antenna I told you not to buy or a cable

that you purchase for five bucks at

Walmart the difference truly is night

and day I've been in many situations

where I've installed antennas that need

a 25 to 50 foot coaxial cable run and

because I use a quality rg6 quad shield

cable there's such little signal loss

that I don't even have to use a preamp

up at the antenna that people get all

their stations and fine in fact a few

months ago I went to an antenna set up

in Hellertown Pennsylvania where the guy

wasn't getting many TV stations on his

TV set I noticed that the cable he was

using was a really cheap white cable

sure enough when the cable was replaced

he went from 14 to 33 channels I

attached a link to various recommended

rg6 quad shield coaxial cables in the

description of this video for those of

you that are considering replacing your

current cable that's going from the

antenna to your TV sets thanks again for
