FAQ: How far can coaxial cable transmit?

Does length of coaxial cable affect signal?

When it comes to signal loss over longer cable lengths, the basic rule of thumb is that a 50-foot cable can experience noticeable signal loss, and a 100-foot cable can drop as much as one-third of the original signal. Therefore, your 15-foot cable shouldn’t be long enough to introduce that sort of problem.

What is the frequency range of coaxial cable?

For typical coaxial cables, the shield cutoff frequency is 600 (RG-6A) to 2,000 Hz (RG-58C). Attenuation (loss) per unit length, in decibels per meter. This is dependent on the loss in the dielectric material filling the cable, and resistive losses in the center conductor and outer shield.

How far can I run coax for TV?

If it is RJ6 you should easily be able to get usable signal up to 150 feet. If it is RJ59 the high frequencies lose signal more quickly so the max length is about half that of rj6.

What is the maximum distance for RG6?


Cable Type* Maximum Distance
RG59/U 750 ft (229 m)
RG6/U 1,000 ft (305 m)
RG11/U 1,500 ft (457 m)

Does length of coaxial cable matter?

Coaxial Cable Length

Coaxial cable comes in varying lengths. The shorter and thicker the cable is rated will determine the strength of the signal transmitted. It is important to choose the right cable length and thickness. In radio systems, cable length is comparable to the wavelength of the signals transmitted.

Does coax length affect SWR?

The ONLY issue coax length has in a basic system is the longer it is the more loss you have. In fact because SWR is a measurement of reflected power and if you measure at the transmitter output your SWR can look better because there’s more cable loss than if it were shorter.

What does 75 ohm cable mean?

The 75 Ohm impedance is a world-wide accepted value for all kinds of coaxial high frequency signal connections. Impedance is another word for the value of electrical resistance for alternating current: An alternating voltage applied at one cable end results into an alternating current flowing into the cable.

Are all coaxial cables the same?

There are different types of coaxial cable, which vary by gauge and impedance. Gauge refers to the cable’s thickness and is measured by the radio guide measurement or RG number. The higher the RG number, the thinner the central conductor core is.

Are coaxial cables still used?

Toss: Coaxial

This is an age-old cable that is still widely used, especially for cable and Internet. Fiber is the biggest threat to the traditional copper cable. Toss. You probably don’t need any more coaxial cables than you already have.

How far can you run RG6 cable for Internet?

As others have noted, 200 or more foot runs are not a problem if the proper cable is used. Under about 150 feet you can get away with most anything.

How far can a TV signal travel?

Commercial Over-the-Air TV antennas are marketed with distance ratings between 20 to 60 miles (for most indoor models) and up to 150+ miles (for ‘extreme’ outdoor models). But, in real-world conditions the idea reception areas for antenna TV are within about 35 miles of local broadcast towers.

How far can you run antenna cable?

with booster it should range around 50 miles, stations are about 30 miles.

Is RG11 better than RG6?

RG6 has higher attenuation level; RG11 has lower attenuation level. RG6 can transmit signals in a higher frequency range than RG6. Because RG11 has lower attenuation level, it can transmit in a father distance: RG6 can transmit signal in a distance of 600m, RG11 can transmit in a distance of 1,100m.

Can I use RG6 instead of RG59?

A basic rule of thumb is to use RG6 for any Rapid Frequencies, and use RG59 for video frequencies. RG6 has an aluminum braid and an aluminum shield. RG59 comes with a copper braid, and in some instances, an aluminum braid and shield, although this is quite rare.

How far can you run RG11 coax?

Distances for different coax cable types and the reasons why—In the field, RG11 coax runs more than 150–200 feet; RG6 coax is for less than 150 feet. However, people use RG6 coax because it is less expensive. The cable used depends on the attenuation desired and length of the link.
