I am running watts. N3OXAug 1, Attached to the grounding bar is the grounding rod, and all the grounds for the equipment. I can make a short video if that helps Orion. You probably won't notice a difference, but RG8 will be better. The question being, how much better? Going to a run gets 1dB of loss, even at The lower the frequency, the lower the loss of RG Is the additional weight of thick coax worth it?

Depending upon how active you are, if it was me, I might wait until I got a good deal on some better coax--unless if you are routinely working signals at the noise floor, 2dB is not noticable. OTOH, if you're all the DX signals, then, well you'd probably swap both antenna and coax for something else.

W4MMC likes this. The correct answer to this is "it depends Longer runs then a hundred ft would require the larger coax also. K8JDAug 1, I have not been active on 10 meters at all yet. I do fairly well on 20 and 40 meters, although the last few nights I have been on a local 80 meter net and am really enjoying it.

I'm likely going to stick with the system I have right now until next summer. By then, I should have some money put aside to get a better mast, and go with a different antenna system. I think I will home brew a mono-band 80 meter dipole so I can take part in the meter net here in Arizona.

The DX-LB, at 32 feet high, is just giving me less than satisfactory results on 80 meters. I'll make a video today of my new config, hopefully I have worked out all the kinks Thanks everyone, Orion.

Was the DX-LB adjusted for 80m? I suspect a full sized 80m dipole will do better, but I don't think greatly better. At 32' it's pretty low, and non-directional. What height are the ends up at? You say inverted V, so the ends aren't very high--try elevating those first, it may reap big dividends. Then see about altering the resonance on 80m assuming the SWR is above say where you want to operatethen work on changing the feedline to something lower loss.

Also, and I'm not sure how applicable it is, take a look into using T-type tuners.Forums New posts Search forums. Media New media Search media. Classifieds New listings.

RtRadio Member Premium Subscriber. Hi,I was wondering which coax is the best for 2 meter ham radio? Joined Sep 20, Messages 6, Location Sector How long of a run? W2NJS Member. Back to the original question, 8U is considerably less lossy than 8X.

Do a Google search for coax cable specs and you'll find the exact data. LtDoc Member. Joined Dec 4, Messages 2, Location Oklahoma. Nothing wrong with using RG-8X for short runs at 2 meters. That 'short run' thing is typically less than 50 feet, or for mobile use. So just how important is ease of use to you? That 'spec' chart for various sizes of coax is a very nice thingy to have around, or at least to compare different cables and frequency usage.

Fractional differences just don't amount to anything significant, so don't get too wrapped up in that aspect. The numbers to the left of that decimal point can make a difference, but they have to be larger than 3 to be very significant. LtDoc said:. That 'manipulate' was explained already.

It's jut easier to bend, thread though tight places, etc. It's also smaller, that can make a difference at times too. Nothing wrong with RG-8, use it.

RG-8X or RG-8U

Please remember that that Times attenuation calculator presupposes that you are talking about decent coax meeting their specs. The US and most European firms make good stuff as do many of the Taiwan factories that produce cable for 3Com, Cisco etc. Much of the Chinese stuff is pure crap. I want to use it for 2 meter ham radio freqs. The 'thickness' of RG-8 can be a problem at times. But, it's certainly manageable in most instances.

If you have to do some very tight bending, and can't find another way of doing it, then RG-8X may be an alternative. If it's a matter of 'looks', then hide it in some way paint it?Read more From all of us here at CB World, we wish you the very best. Contact CB World! It is more durable, thicker, with a stranded center which means it is more difficult to damage than a solid core coaxial cable.

Only a few types of coax, namely RG58 and RG8, are available as stranded. There are many rumors and theories for what LMR may mean but nobody really knows for sure. For example, RG59 cable originally had a diameter of. While these measurements have changed over the years, the names of the cables have stuck.

There are many types of RG cables and this article will only review the most common variants. Typically, RG cables have a 50 or 75 ohm impedance.

Some off-shoot cables have different impedance, but all the standard RG cables covered here will be one of those two. LMR cable is owned by the company Times Microwave. For example, LMR has a 0. LMR, like RG, has a few main types that this article will cover but off-shoot versions are also available. RG58 is a common cable used for 50 ohm applications, measuring 20 AWG.

Today it is mostly used on devices that need only audio or video instead of both, like a HAM radio or security camera. It is mainly used for amateur radio. It used to be used for cable television but has largely been replaced by newer, more effective coax cables.

Also a 75 ohm cable, RG6 is better shielded and carries HD signals for greater distances. Currently, this is the standard cable used for cable television, satellite television, and cable internet modems. The thickness makes it less flexible but ideal for long runs.

It is commonly used in place of RG6 when distance is an issue. RG is a thinner variant of 50 ohm cable at 26 AWG. Its thinness provides extra flexibility but signal loss is higher compared to RG This cable is most commonly used for Wi-Fi pigtails. RG is also 50 ohm and used for high-frequency signals, with a maximum attenuation of This cable is very thin at 30 AWG, making it best for short distance runs.

RG is an alternative to RG LMR is very thin, being designed to replace RG It possesses more than double the shielding of RG, cutting down on signal loss significantly.

LMR was made as a replacement for RG LMR also replaces RG58 and has the same 0. The difference is that LMR has a slightly thicker center conductor, allowing it to cut down on signal loss a bit better than LMR Instead, it was built to be a very thick and powerful cable for long distance runs.

LMR is primarily used for powerful satellite frequency transmissions, being able to run signals from to feet. Coax Coaxial Cables.QRZ Forums. What it the difference and benefits of one vs the other. N6DCNSep 5, RG8X is "mini But it's supposed to be. It's usually very flexible. As a "mil spec" product, it was discontinued 20 years ago; however as a "commercial" product, anybody can make and sell it and it doesn't have to meet any particular specification.

Thank you for your help. Great explanation. Hi, I have rg-8x now but will change to rg shortly. I wished I would have gone with to begin with. I need a buriable coax and 8x will not last long buried. I respect his opinion more than most.

He knows!!! I highly respect his opinions. Good Luck! K2PJWSep 5, Another note is that 8x is not very useful above 50 mHz due to losses. I like 8x for portable use, it's better for RF than RG [but is a little bit thicker and heaver] but a great deal easier to handle than RG Sometimes it's hard to hold up with a dipole - if it is a long run, you can use 8x to the ground then the rest of the way if you want.

Personally, I have used RG-8x for all my HF antennas, but I don't use an amp either - when I get an amp, I'm going to have to upgrade some or all of my coax. NA0AASep 5, I don't think classifying rg-8x as an inferior product as compared to rg is not exactly what 'WIK was trying to portray.

First, there are good and bad products in both classes of cable.

Second, as an engineer, I recognize that each type of cable may be more appropriate in given situations. For things like jumpers below 30 mHz and probably higher, a good brand of rg-8x is entirely appropriate. As pointed out, it is appropriate to use for hf dipoles if the center isn't supported. I guess my point is don't say rg-8x is inferior just recognize it has different design criteria and is more appropriate for certain applications. I have runs of RG8x into the woods for HF loops and dipoles behind my house, as long as ft, with no problems on M bands.

If I had a reason to put up antennas for higher bands with long runs I would use a better variety of coax. I only have about 50 ft runs of that line to the antennas. K8JDSep 5, Correct coax feedline selection depends on a number of factors.
