Cell Phone Jammers are widely used in various fields to block unwanted signals. When it comes to the coverage direction of signal blocking, there are two basic classifications: omnidirectional antenna coverage and directional antenna coverage. However, the idea of simultaneously configuring both types of antennas in a Cell Phone Jammer and quickly switching between them is not as simple as it seems.
Implementing the simultaneous configuration and quick switching of antennas in a Cell Phone Jammer is not an easy task. Unlike circuit switching in electrical circuits, RF signals cannot be simply understood as circuit switches. RF signal switching requires power dividers or dedicated RF switching devices. However, the availability of such RF switching devices is limited due to the rarity of their application scenarios. Additionally, there are two other reasons that limit the feasibility of power switching:

- Signal Attenuation: After going through a power switching device, RF signals would experience at least two additional RF interfaces for signal input and output. Each additional RF interface would cause signal attenuation.
- Production Cost: Considering the comprehensive production cost, it is not currently feasible to rapidly switch the antennas of Cell Phone Jammers between directional and omnidirectional modes. The limited budget and demand from customers do not justify the investment required by manufacturers to implement such functionality.
While the idea of quickly switching the antennas of Cell Phone Jammers between directional and omnidirectional modes is not completely impossible, it is currently not practical due to the limitations mentioned above. Manufacturers of Cell Phone Jammers have not prioritized the implementation of this feature, considering the cost-effectiveness and the relatively low demand from customers.
