Is LMR400 the same as RG-8?
RG-8, RG 213, RG 214 coaxial cables are the same physical size as LMR-400 – yet their attenuation is up to 40% higher and they have significantly inferior RF shielding performance.
Which is better RG8U or RG8X?
Changing the able to RG-8X drops the loss to 4.5 dB, which is only a minor improvement. (4.5 dB loss corresponds to 36% of the power makes it through.) However, using RG-8U type cable decreases the loss to 2.4 dB (58% of the power makes it through the cable), so clearly the larger cable size has an advantage.
Is LMR400 the same as CNT 400?
CommScope CNT-400 is their Ultra Low Loss Equivalent of Times Microwaves LMR-400. Famous for years as a manufacturer of high quality Coaxial Cable, Commscope now offers this option for quality cable installations.
Is RG8U good for VHF?
The ISAF Offshore regs state that RG8U cable is acceptable for VHF installations over 50 feet in length and that RG8 is good/ aceptable only up to 50 feet.
What is the difference between rg8u and RG213?
RG-8/U is the same diameter as RG-213 (. 405″), while 8x is much smaller (. 242″). RG-8/U is also much closer to 213 in terms of loss, while 8x suffers almost twice the loss per 100 feet.
What is RG8U used for?
Coaxial cable RG8U 1154 is frequently used in the transmission of communications signals. More specifically, audio, video, or network signals. You will most likely recognize these cables if you have looked at the backside of your cable box or modem.
How many watts can RG8U handle?
The maximum power handling is 875 watts.
Which is better a lmr400 or a Rg8 cable?
Generic LMR400 is usually just a clone of the original, and meets similar specs. LMR400 would be OK for about any frequency from 2M and down. RG8 or RG213 type cables are OK for 100ft runs at HF, but get lossy at VHF and above. At UHF, 100 ft of any type of small cable is going to have a lot of loss.
Which is better a rg213 or a lmr-400?
For VHF (50 MHz, 144 MHz, and 222 MHz) LMR-400 is preferred by many because it has somewhat lower losses than RG213/U in runs up to around 70 feet. However, there are a lot of antenna installations that use RG213/U at these distances on VHF. To go around a rotor most people use RG213/U while some use LMR-400 “superflex”.
Which is better a Rg8 or rg213 cable?
RG8 or RG213 type cables are OK for 100ft runs at HF, but get lossy at VHF and above. At UHF, 100 ft of any type of small cable is going to have a lot of loss. 7/8 inch Heliax (or larger) would be a better choice, but that is very pricey.
What’s the difference between RG-11 and LMR cables?
RG-11 is a higher gauge cable used for CATV, HDTV, TV antennas and video distribution. It has an impedance of 75 Ohm and provides 3 GHz frequency. LMR® is the newer generation of RF coaxial cables. They provide greater flexibility, ease of installation and lower cost.
