Transmit power for Fortinet APs is defined as the EIRP1 (Effective Isotropic Radiated Power) at the antenna and includes the antenna gain. (This is important to remember; transmit power is not the power at the connector.)
Rechargeable Panasonic Eneloop AA batteries (non-Pro version): When I first became a licensed ham radio operator in the late 1990s, sealed lead acid batteries were the primary battery power source used for field radio operation.
In addition, 12-volt batteries are nearly ideal for amateur radio use since most transceivers are designed to operate with 12-13.8 volts DC +/- a modest margin. There are some negatives compared with more modern battery chemistries, however. For one, SLA batteries are much heavier than the batteries we'll discuss in the following sections.
The final type of battery chemistry we'll cover here is my favorite of the bunch. There are good reasons why Lithium Iron Phosphate batteries have become one of the choice rechargeable batteries for field radio use. Any cons?
There are good reasons why Lithium Iron Phosphate batteries have become one of the choice rechargeable batteries for field radio use. Any cons? Yes…while they're lightweight, LiFePo4 batteries aren't as compact as Li-ion battery packs. But the primary negative here is the price.
While, admittedly, these batteries are not typically an option because of their limited capacity and energy density, they can still be a very practical power source for portable receivers and even a few QRP transceivers.
