The larger the working radius, the higher the price
Cell phones today have no GPS and are hardly popular. Not only in navigation, but in many mobile applications, GPS is required to locate the city you live in.
GPS positioning can bring us a lot of conveniences, but it can also put us in danger. The number of cases tracked by GPS is not the majority. We know from past stories that many criminals use GPS to stop crimes for their victims. GPS-equipped devices can be the accessories they function with, such as our mobile phones, smart watches, or even cars or other products.
A small GPS jammers with about 10 watts of power can even jam an unmaintained C/A code receiver at a range of 30 kilometers.
Devices used to interfere with GPS signals vary by type. Portable interceptors are the most popular GPS interceptors. Portable jammers are easy to use and carry and are significantly less expensive than larger GPS jammers. Portable jammers typically cost between $80 and $200. How to choose a clean GPS signal jammer for you? Buying a frequency suppressor is really hard for the layman. In general, the price of a GPS jammer can follow a rule of thumb: the larger the mission radius, the higher the price.
The shielding range of conventional signal jammers is about 30 meters, and some models of high-end detectors can even shield GPS signals 1.5 kilometers away. There is no doubt that these blockers are much more expensive than common inhibitors. Besides price, there are many other aspects to consider, including construction and durability. If you're installing a GPS signal shield in a larger outdoor area, you'll have to pay more for a high-end waterproof design.
