Is LMR400 same as RG-8?
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 LMR400 or RG213?
Typically, the larger the conductor, the lower the attenuation. Since LMR400 has a larger conductor than RG213, the conductor size accounts for RG213 experiencing more signal loss than LMR400….How Do They Compare?
| RG213 Loss (Attenuation dB/100ft | LMR400 Loss (Attenuation dB/100ft) | |
|---|---|---|
| 1000 MHz | 8.2 | 4.1 |
What is RG-8 cable used for?
RG8 is a type of coaxial cable suitable for use in carrying radio transmission signals. They are found mostly in audio control rooms, radio stations or as connections for external radio antennas.
How many watts can LMR-400 handle?
| Power Capacity (In watts 104 °F, 40 °C) | ||
|---|---|---|
| MHz: | 30 | 450 |
| LMR-400® | 2100 | 550 |

What is RG213 used for?
RG213 coaxial cable is suitable for use in VHF (Very High Frequency) and UHF (Ultra High Frequency) radio communications, data transmission, and broadcast applications. RG213 coax cable is also applicable as an antenna feed cable when low signal loss and high operating voltages are required.
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 Rg8 or bury-flex coaxial cable?
LMR400 has a solid aluminum center conductor, and as such, it doesn’t like a lot of stress or continued bending. Bury-Flex is a better choice if a lot of flexing will be anticipated. MM0KMK likes this. RG8/U “type” coaxial cables can run the gamut from very good to absolutely dismal.
What’s the difference between Rg8 / X and rg213 / U?
The “new” specification is RG213/U which is the equivalent of the old true RG8/U specification. For HF operation you are not going to see any real difference between RG8/X (smaller diameter cable than RG213/U), RG213/U, or LMR-400.
