2, Small size:

Retevis RT97 Portable Repeater measures 26*21*7cm. 4000mah lithium battery volume: 24*20*7.5cm. The antenna is 40cm long after being folded.

3, Easy to carry:

You can use a dedicated carrying system. You can also DIY piggyback your own system. A small backpack can hold all the equipment. The single person carrying, car travel, can easily travel.


This size of the backpack has a lot of space left. You can build a system with a smaller backpack. You can also use a large backpack to solve the heat problem. This will not overheat when the boot time is longer.
