How to Choose and Use the Best Marine VHF Antennas?

For anglers, finding the best VHF antenna can signify the difference between enduring a skunk or finding a great bite. But seriously speaking, having the right kind of VHF type of antenna can save you from being stranded or could save you from a seeming serious accident.

Even the world’s best and premier marine radios are not likely to deliver their optimum performance if you have them connected to the wrong kind of antenna. These antennas are comparable to how the tires of a sports car work, where it serves as the vehicle’s only point of contact to the ground, giving it enough grip and traction when it is already racing around in a track.

In the case of a radio, the only point of contact that it has got with the outside world is through its antenna. Should the race car tires are inferior in quality, then there is no way you can expect it to perform well and deliver its very best. Similarly, any radio will require a well-matched load or an antenna that will help it facilitate the efficient transformation of electrical energy into radio waves.

Of paramount importance also about marine VHF antennas is that they need to be well designed in such a way that it will allow the radiated waves to travel in a particular desired direction.

Needless to say, there is no use in pointing your radio was up into space if the contacts you have are around sea-level only. A shoddy, inferior quality antenna will never be capable of delivering the required good match. It may even render you to question your installation work and put you in doubt whether your radio equipment is indeed in tiptop working shape or not.

Hence, we encourage you to use only a high-quality antenna created by no less than a reputable manufacturer. Below are some points you may need to take into account before purchasing an antenna.

Range

The higher you have your antenna above the water, the greater distance that it will be able to achieve. VHF radio waves tend to travel in straight lines. As far as communications range is concerned, oftentimes it will be pertained to as the “line of sight”. Simply put, it is of paramount importance that your antenna can “see” the antenna at the other end. Expressing this more succinctly, there has to be unencumbered access between these antennas.

Communicating by virtue of VHF is limited to around 35-50 miles, and this will highly depend upon the height of the antenna. Sails are considered to be in a more advantageous disposition here since you can mount the antenna right at the top of the mast and therefore allowing you to reach great distances.

Mounting

The manner in which you will have your antenna attached to your vessel or boat will depend upon the inherent features of the boat itself. Three of the most utilized and most popular mounting methods are as follows:

Rail Mounting

This will come in a variety of sizes, and usually have ratchets that allow for easy lowering.

For sailboats (Mast Mounting)

Surface Mounting

If there is an available horizontal or vertical surface you can mount them to, you can take advantage of flange mount for this purpose. Most of the time you will make use of a ratchet mouth that will adjust to the mounting surface slope. It will also allow you to easily lower the antenna.

Mounting Location

We have here what is considered as the general mounting guidelines:

  • Mount the antenna as high as possible, this will allow you to take advantage of the line-of-sight. 
  • Install the antenna at a safe distance from metallic objects, especially large-sized ones. 
  • Don’t install your antenna in close proximity to another
  • Install your antenna a minimum of 3 feet away from marine radio.

Significance of Industrial Machine Repairs

Underestimating the benefits of industrial machine repairs is taking a toll on the bottom line. The saying “if it is not broke, do not fix it” is way too often the way a bit of perspective construction equipment maintenance. Precisely why might you spend on service on the equipment of yours if there is absolutely nothing wrong with it? Truth be told, there are several reasons. Building equipment is an investment – one which calls for money and time to keep in optimum shape.

Benefits of Industrial Machine Repairs and Maintenance

Preventative equipment maintenance is crucial to extending tools life and eventually saving you money and time. While the perception of yours might be that paying for preventive maintenance is needless spending, the simple fact is the fact that without it, you are frequently left with much more costly repairs. We feel in the benefits of preventive maintenance, and after reading through over the following factors, we believe you’ll, also.

Keep Equipment Running Efficiently

A brand-new piece of gear is in optimum shape. It operates efficiently. The definition of effectiveness for every piece of equipment might differ, but equipment that is new operates like a well-oiled machine? and that is great for business.

When tools run efficiently, plans get done on or even ahead of time, and the bottom line of yours does very well. Keeping that optimal, like-new condition is essential to keeping that level of gear efficiency. If maintenance suffers, and so does efficiency. When productivity suffers, and so does the bottom line of yours.

Small Problems Grow Over Time

We have all witnessed it before? food is not operating precisely the way it used to, though it is not impacting the job of ours in a huge way, therefore we continue, often even making changes in just how we make use of the portion of gear to preserve things moving. While it might seem, this way is the most effective method to receive the task finished in the temporary, it can cause you major headaches down the road. In case of food is not operating the way, it should? regardless of how little? chances are it is going to grow into an even bigger issue if it is not addressed.

Fixing Big Problems Expensive

While it might seem as it does not make sense to invest the money and time to get it inspected or perhaps repaired when you are in a position to work around it, the simple fact is actually waiting is actually going to set you back a lot more. Bigger, much more complicated repairs are available with a larger price tag. Think of much more than components? sure, a considerably more complicated issue will probably come with having to change more and/or larger areas that are pricey, though it does not end there.

Big problems typically convert to more downtime, and a lot more downtime means you are abruptly behind schedule and not able to have a brand-new project. In case you’ve workers on the clock which were slated to work with this piece of gear, right now you are paying them despite the reality that they’re not able to function temporarily due to gear downtime.

Clearly, in case you get to this stage, you will do just what it takes to get the gear back up and working quickly, but that very has an extra set of costs. Expedited shipping for parts includes a price tag. All of it adds up. Bigger issues have a snowball effect. Do not hold out for the larger problem – purchase the little one.
