What to Look for When Buying a Coax Cable for VHF Radio
Suitable coax type – In terms of coaxial cable types on the market, I can see that there are many different models with diverse advantages for you to check out. I can help you choose the most suitable one for VHF radio to transmit and receive signals on the marine band, and to respond to your personal needs.
The RG-58, RG8, RG-8X, RG-213, and LMR-400 marine coax cable are those coax types that appeared in this article so I will go into the details for each of them below. The standard RG-58 coaxial cable is really flexible and easy to run at home. It works best for signals under 100 Mhz for the marine band has higher losses.
While the RG8 enables 34% less signal loss than RG-58 with a more stable transmission line, an RG8 coax provides great retention with the best compromise for flexibility and loss. It cannot carry pure video signals. RG-8X is the miniature and thinner version of RG8, which produces the same quality.
Besides the difference in their outer jacket coating, RG-213 and RG8 cable are not that distinguished from each other. They are built for high-powered uses and can be buried underground. In comparison, the LMR-400 is newer and made intentionally to replace RG8 with an ultra-low loss and highest level of propagation.
Those are among the most common coaxial cable for VHF radio types being reviewed here so I hope you can somewhat acknowledge their main strengths via this section. You should go for the most suitable antenna coax with your personal purpose of use and not the strongest one, based on my experience.
Reliable connectors – As far as I am concerned, two popular VHF antenna connector types available for a VHF coax cable are male PL-259 and female SO-239. Antenna coaxes with both male and both female connectors are more common. Or they can include male on one end and female on the other sometimes.
Regardless of the connector type on this cable, your electronic appliances need to have the same connectors with the coax for connection and ready to use. There are a few things that you should need to focus on when checking out the connectors of a VHF radio antenna cable and I will list them out here.
The majority of these cable connectors are soldered and pre-attached to the antenna coax. Non-molded ones are also suggested as another great option. The extra heat shrink on the connectors can prevent moisture from getting in, so it is quite a crucial must-have and should be of good watertight fit.
Another detail is that the connectors require to have the appropriate length for screwing down your electronic devices. In many cases, short connector plugs have blocked the outer sleeve from going in at a sufficient depth. As a result, this entire coax is worthless. I advise you to give it a direct test before buying if possible.
Frequently Asked Questions
What are the most trusted coax cable for VHF radio brands?
It is a true challenge to filter out some of the most trusted coax cable for VHF radio brands available among thousands of them in the world. But if you ask me, I would definitely recommend you reach out to Steren, MPD Digital, Bingfu and Times Microwave in order to obtain the best coax for VHF/UHF.
I like how the overall price range for their coaxial cables is fairly reasonable as well as the diverse list of different lengths to choose from. These providers have all sorts of coax types for sale like the RG58, RG8 or LMR-400. They all adapt well to tuners, switches, analyzers and meters with the same connector.
These brands have a lot of worldwide distributors, both in physical stores and online platforms. Hence, you can either purchase a coax cable from such sellers or the manufacturers themselves. Their antenna VHF cables always come with full warranties and a return window for you to deal with the defections for free.
How to use it?
Signal boosters – Apart from enhancing marine radio signals, you could also use a coaxial cable to connect to cell phone boosters. In terms of positioning, an antenna is usually installed outside of your house, whereas the second one is on the inside and the amplifier to enhance these signals is placed indoors as well.
A coaxial cable has the responsibility to tie these 3 electronic devices together and helps strengthen your cell phone signals better. If you choose to use this technology, you are able to boost a weak 3G 4G cellular signal. But remember that this coax cannot create any signal on its own nor enhance landline WiFi.
Basic RF – The most basic function of a VHF coax cable is to carry RF (radio frequency) signals from one point to another through its center conductor and connectors on both ends. RF waves would be generated when an alternating current moves through a conductive material, like in this case with metal coax.
Cable Internet (copper-based) – Copper-based coaxial cables can work as a cable Internet at home. This cable would be piped into your house from a local cable service provider. You plug its connector into a router or cable modem, which can be plugged into a TV or computer to gain the Internet and viewing access.
Ham radio – People use ham radio as a means to wirelessly communicate via airwaves. A coaxial cable helps connect it with an antenna so the signal would be stronger. The good thing is that you can set up a ham radio in the middle of nowhere and it does not need any Internet or cell phone technology to work.
How to take care and maintain it?
Here are a few simple steps to clean up a VHF antenna cable. First, both of its connector ends have to be disconnected. After, you have to get a piece of cotton ball and place it on top of an open bottle with rubbing alcohol. When it is quickly turned back upright, this solution will saturate the cotton ball a little.
Next, use tweezers to grab the cotton ball but make sure the side with the alcohol is on the opposite of the tweezers. The last thing to complete is to rub the cotton ball into the connector’s grooves and be careful not to accidentally break or bend the center stud that enables the signals. Repeat until all dirt is removed.
Based on my experience, you should collect the whole coaxial cable and tie it up with another string for better storage when not in use. Also, it should not be exposed for long hours under bright sunlight or rain. Place the antenna cable far from the reach of children and do not detach its components without skills.
Though the majority of available coaxial cables for VHF radio are mainly built with strong and durable materials, their general lifespan can only be extended with your care. Without proper maintenance throughout continual use in a marine environment, even the finest antenna coax would not be able to last for long.
Where can I buy it?
There are several locations where you can reach out quickly and purchase a VHF cable and I will recommend going to Walmart, eBay, Home Depot, Best Buy, Amazon and Lowes. They are both trusted local chain stores and online shopping websites, so the product quality, in general, is amazing and worth trying.
Not only are the coaxial cables here diverse in manufacturers and prices, but they are also made with the highest standards and always go with warranties. The reliable brand names above have their antenna VHF cables sold at these addresses. Therefore, it would be really beneficial for you to buy a coax there.
Conclusion
If you are having a VHF radio and wish to use it at the marine frequency band, I believe a sturdy and effective coaxial cable is exactly what you need to get. It can help you out a lot when it comes to boosting marine signals and survives a difficult environment out in the sea. Do not hesitate to purchase a coax right now.
