The trailer unit has a tilt-up tower and a wide variety of antennas. |
 Inside view of trailer. Communications capability includes UHF, VHF, GMRS, MURS, CB, FRS, HF, and wireless internet. |

|
Man-portable units are part of the equipment available. |
|
UHF repeater in a box |
|
|
VHF in a suticase. These are great ideas for any quick response team. The higher power available from the 'base/mobile' radios will give greater range than a simple handy talkie. |

Portable unit made from an old PC case houses several radios and a cellphone. A gel-cel and charger is built into the bottom of the case. It weighs about 20 lbs. |
|
From top to bottom, 440-MHz ham, 2-meter MHz ham, CB, and FRS. Note the FRS 'emergency boost' switch.. ahem.. |
This view shows how the connectors are arranged. It looks like the PC power supply has been kept, but I would think that it's only the chassis for the bulkhead power connector. (The usual PC supply can provide a reasonable amount of 12VDC power, but the voltage is not high enough to keep a gel-cel charged properly. Additionally, most pc power supplies require a minimum load in order to not shut down. usually a 5 amp load on the 5V output is sufficient, but that wastes 25 watts and makes alot of heat.) |
