What coax cable is best for ham radio?
What coax cable is best for ham radio?
All three of these cable types will handle 100W or more at frequencies below 500 MHz, which covers most ham transceivers. If you are running more than 100W, you should check the power specification of the cable you are using….Hey, Which Coaxial Cable Should I Use?
| Type | Diameter | Usage |
|---|---|---|
| RG-8U | 0.405 inch | General purpose coaxial cable, best for long cable runs |
What is RG8 coax 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.
Is RG8 coax better than RG-58?
RG8 is a thicker 50 ohm cable, at 12 AWG, that can provide a stronger signal than RG58. It is mainly used for amateur radio. There is also a version called RG8X, which is thinner at 16 AWG but provides similar signal quality.
How far can you run RG8?
75′
The cable length will determine the type of cable that should be used. The maximum distance for RG-58 cable is 25′ from the subscriber to the antenna, including the lightning protector. The maximum distance on RG-8 is 75′.
Does coax length affect SWR?
Coaxial Cable Length Does Not Change Antenna SWR.
Is RG8X good for VHF?
Best choice in my opinion is RG8X because it’s less ‘lossy’ than RG58 but flexible and easy to handle. The bigger diameter cables are necessary for longer runs, over about 20m. The PL259 connector you link to is correct for RG8U/ RG213, you’ll need to find the correct size PL259 once you’ve selected cable size.
How many ohms is RG8 coax?
RG-8 is similar to RG-6, but unable to carry pure video signals. It has an impedance of 50 Ohm and is used in audio control rooms, radio stations or as connections for external radio antennas.
Can I use RG6 instead of RG8?
RG6 cables are mainly used for cable internet, cable TV, and that is the most significant difference between the popular RG6 coaxial cables and RG8 cables. RG8 is unable to carry clear video signals because of its design and, consequently, is more appropriate for radio signals.
Is LMR 400 the same as RG8?
Conclusion of LMR400 VS RG8 The major differences between the LMR400 and RG8 are the attenuation and frequency. The Attenuation at 1 GHz of LMR400 is 4.25 dB, while the Attenuation at 1 GHz of RG8 is 8 dB. Additionally, the maximum frequency of LMR400 is 6 GHz, while the maximum frequency of RG8 is 1 GHz.
Which coaxial cable has the least amount of signal loss?
Larger coax cable (example LMR-400, Wilson-400, SureCall SC-400) will have less loss. For long cable runs (100 feet+), using Cable Type 400 or even better Cable Type 600 Low Loss Coaxial Cable is best for least amount of signal loss due to cabling.
Can SWR be too low?
An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. Safe operation of your CB should be with an SWR of 2:1 or less. Most people would prefer to be 1.5:1 or less.
