Pig Radio Mobile Antenna Mount Considerations


Mobile communications antennas come in all different sizes and shapes. They also are designed for operation on various eq usually divided straight into various communications services. Some the marketing communications services add the business band, maritime portable, citizens band (CB radio), and so forth. No matter of the consistency or band involving the antenna generally there are several standard considerations to believe through when it comes to both the type and placement of mobile broadcast antenna mounts. This post will review the key issues and discuss options to take into account.

Each type involving antenna and build needs to have got a good floor and a fine ground plane. While the dependence on this specific will vary by frequency, having the good ground and ground plane is usually desired for every frequency in practical terms. Many base station antennas make use of the physical terrain, enhanced through typically the use of floor radial wires delete word, to help kind a take-off stage for radio dunes being transmitted. Upon a car the particular flat part of the particular top of some sort of car forms some sort of ground plane regarding a mobile antenna. Location of the particular antenna on of which ground plane becomes important. A middle location produces the particular most nearly game pattern. A location towards one direction produces an pointed pattern in the opposite direction using less effectiveness within the direction for the antenna. While typically the center of the roof of any vehicle can be a great location for a mobile antenna mount it may be hard to work typically the coaxial cable to the radio. An easier solution coming from the coaxial cable’s perspective may end up being the trunk. Several people opt regarding a trunk lips mount. A attach in the centre of the top requires drilling a hole in the motor vehicle while a trunk area lip mount makes use of set screws to carry the mount towards the lip of the particular trunk.

Radiation associated with just as much radio rate of recurrence energy as feasible is both a new good thing and even a problem. In the event that the antenna is definitely mounted in typically the center of the roof, the roof works as a shield and prevents the body from being extended by the antenna for the extent useful. In case the antenna will be attached to the trunk area lip then it is spraying stereo frequency energy right at the people of the auto right through the rear window in the vehicle. The amount involving radio frequency vitality and potential associated risk varies with regularity and amount associated with power used mainly because well as amount of time used.

Other options exist and a review associated with catalogs and blogs on the net can provide good top quality pictures and evaluation of the positive aspects and disadvantages of many of them. Anticipate finding antennas mounted about the gutters involving the roof, various sides and middle of the start, side panels of the vehicle, front bumpers, back bumpers as well as the engine cover. Remember that right now there is no totally perfect solution along with the best solution intended for a particular man or woman will depend on the type regarding antenna, type of vehicle, budget, complex ability, time, persistence, etc..

No matter area and shape of typically the ground plane, an excellent radio frequency (RF) ground is required. Think of this example — if negative stereo frequency energy still cannot flow to floor positive radio rate of recurrence can’t flow off of the symbolizing element of the particular antenna. I usually tell new pig radio operators there are three things you need to recognize about mobile antenna mounts – coffee grounds, grounds and reasons!

Once you figure out the location of the antenna attach and how in order to achieve a good stereo frequency ground (usually using a wide secure or mesh — radio frequency moves along the OUTSIDE involving metal unlike electricity) then think about the SORT of mobile antenna mount. Remember of which search engines like yahoo and blogs and forums are wonderful things with regard to researching types and locations of antenna mounts. Any a single catalog or website likely will not have just about every imaginable sort of antenna mount. Also remember that will every antenna install will have both pros and cons. washable fire radio strap can review a good example of a couple of or three supports and you will likely get the idea.

Consider the classic ball and large spring and coil mount. For the large whip type of antenna this may be a good but perhaps not perfect selection depending on your current preferences. Also consider the less sturdy yet less “springy” fixed trunk lip attach. Now – when you hit a huge tree branch with this whip style antenna while driving there will likely be different final results with the two mentioned here mounts. Typically the large spring in the ball in addition to spring mount is going to have a lot of “give” and will permit the whip to stay mounted on the attach with all the mount being mounted on the automobile while the beat slides under the particular tree branch. A fixed mount affixed to the lips of the trunk area by set screws likely gets sculpted off from the trunk and maybe the trunk lip becomes bent.

There are generally disadvantages to typically the sturdy ball plus spring mount which in turn requires four good-sized holes within the body associated with the vehicle to be able to mount it. 1 disadvantage other than potential rust plus reduction in trade-in value is the particular motion of the whip while traveling. A mount with out a spring will mean a steadier mix than one which has a spring. Remember : the heavier typically the antenna the weightier the mount. Much larger ham radio antennas are taken simply by amateur radio providers to metal fabricating shops to get customized. Also request your local auto dealer for tips as well seeing that anyone that works together trailer manufacturing, and so forth.
