The market has a variety of long-range antennas. Read the specification of a model. This will help you make a precise decision.

Durability & Flexibility

Although most premium-quality long-range antennas for Garmin Alpha 100 come with durable and flexible design. But it is crucial to check it by yourself.

Durability will ensure the longevity of the device. Nobody wants to invest in a cheap product providing short-term service. Devices with a rubberized exterior, gold-plated interior contacts, etc., will surely give you long-term service.

While flexibility is also important, high flexibility gives the users benefits in carrying and using the device with the Alpha 100. 

Long Range

Long-range antennas are designed to receive signals from long distances. As a result, monitoring or tracking your dog’s or furry friend’s movement on different terrains becomes convenient.

Price is always an essential factor. We all set a budget before buying a product. At the same time, we consider purchasing a product that is efficient enough and meets your requirements.

On the other hand, a directional antenna gets a signal from a specific direction. In this case, if you are unaware of your pet’s location, tracking or monitoring becomes difficult if you don’t direct the antenna to your dog’s location.

I recommend buying an omnidirectional long-range antenna for Alpha 100.
