Which is better 50 ohm or 75 ohm?
Especially when it comes to 50 Ohm vs 75 Ohm coax cables.
In short, cables are measured by impedance, how much resistance there is to the flow of electrical energy.
The smaller the Ohm, the better the performance.
So a 50 Ohm cable provides much better results than a 75 Ohm cable..
Is rg11 better than rg6?
RG11, because of its bigger size and better handling of attenuation, is superior when it comes to preserving signal quality than RG6. It’s also able to work at much higher frequencies than RG6 due to it having less signal loss. … RG6 is the more familiar standard, particularly when it comes to satellite cables.
Can I use a satellite dish as a radio antenna?
You can use a satellite TV dish antenna for amateur radio use but how you use it depends on what frequency you want to operate on. … Unfortunately you can’t easily reuse the satellite TV LNA and down converter (LNB) because it is designed for receive only and you will want be able to transmit.
Can I use 75 ohm coax for CB?
RG-59 and RG-6 are 75 Ohm coaxial cables designed for cable television applications, they tend to have wide frequency response and low line loss. … You can use these cables with a 50 Ohm amateur radio antenna system, but because of the impedance mismatch, your SWR will be a little higher.
How many watts can LMR 400 handle?
Power Capacity (In watts 104 °F, 40 °C)MHz:30450LMR-400®2100550Click here to view POWER CHART FOR ALL CABLE TYPES
What is better rg6 or ct100?
The real difference is the loss, RG6 has solid polythene insulation, whereas CT100 is semi air spaced and larger diameter. The UHF loss is significantly less (about half as much). Use CT100 for aerial signals and it good for distribution too and fits F connectors properly.
How far can a 5 watt ham radio transmit?
So according to our rule-of-thumb, 2 people around 6 feet tall using a 5 watt handheld two-way radio, used on flat ground with no obstacles, will have a maximum range of approximately 6 miles.
How high does a ham radio antenna need to be?
A beam type of antenna at a height of 70 feet or more will provide greatly superior performance over the same antenna at 35 feet, all other factors being equal. A height of 120 feet or even higher will provide even more advantages for long-distance communications.
How do you match a 75 ohm to a 50 ohm?
So you have an approx 75 ohm impedance antenna and you want to get the best match you can. Take the wavelength of the frequency, multiply it by the velocity factor of your 75 ohm matching coax and multiply again by 0.0815. For example.
Is rg6 OK for satellite?
RG6 is used for most satellite cables Properly made RG6 cable should give you the ability to get a stronger signal over a longer run, which is important for satellite TV since there’s a lot more signal there. Antennas are often OK with RG59 cable but do just fine with RG6 as well.
What is the best coaxial cable for ham radio?

Can a TV antenna be used for ham radio?
Ham radio is not an inexpensive hobby, and you do need an outdoor antenna, way up as high as you can get it unless you live in an area surrounded by nearby repeaters. TV antennas can be carefully modified for your ham activity.
Is LMR 400 the same as rg8?
LMR-400. LMR-400 is arguably the most common LMR cable, being a replacement for RG8. There is also a version called LMR-400-75, the only LMR cable capable of running at 75 ohm.
How can you tell the difference between 50 Ohm and 75 Ohm BNC?
Basically, 50-ohm BNC connectors are used for older analog video applications. But for higher performance A/V applications like HDTVs, 75-ohm BNC devices are necessary. 75-ohm BNC connectors can, however, be used for analog purposes.
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 rg8x handle?
700 wattsrg8x in the mobile is well safe for 1kw. anymore and id go with times lmr 300. with deadkeys of 700 watts.
What does RG 6 stand for?
Radio Grade 6Acronym. Definition. RG6. Radio Grade 6 (cable)
Can I use 75 ohm cable instead 50?
3 Answers. Sure, you can use 75 ohm coax instead of 50 ohm. In some cases (such as feeding a dipole), 75 ohm coax may be a better match to the load than 50 ohm. … A 75 ohm load on a transmitter designed for a 50 ohm load is only a 1.5:1 SWR, which isn’t that bad.
