1.Maximum Reflection Coefficient: 0.11 (1.25 SWR) over entire frequency range.
2.Typical maximum power handling capability for the Type N and
3.Option 013 furnished with stainless steel Type N female connector. Option 012 furnished with Type N male connector.
Option 006 adds additional alignment holes.
CAUTION | The power that can be handled will be a function of the size of the center |
| conductor. The majority of the heat flow will be via conduction. The weak |
| point is the coax portion. The waveguide portion is capable of higher power. |
| These numbers are assuming an ambient temperature of 25 degrees |
| centigrade and an altitude of sea level. Higher ambient temperatures and |
| altitude would degrade |
