Make sure to read the specs and measure the antenna. A VHF antenna with 25% or 38 MHz of usable bandwidth is pretty unusual. Bandwidth is defined as the range of frequencies where the antenna will show 2:1 or less SWR and a more typical bandwidth is on the order of 10% (that's the rule of thumb for a plain 1/4λ whip over a good ground). So this probably means the antenna can be tuned in the range of 136 to 174 and they've centered it at 145 MHz from the factory to be sold to ham customers. The same antenna might come tuned to a different center (or just not tuned) from a commercial supplier. It's possible this particular antenna does actually have such a wide bandwidth but the radiation efficiency will be very low, meaning it's not going to perform all that well on the air with a lot of loss in the matching network. The devil's in the details. You generally can't have everything, so wide bandwidth comes at a cost in performance. But since you're presumably after a ham antenna for 2 meters we really only need about 3% bandwidth to cover our whole allocation of 144 to 148 MHz.

I have several KG-1000Gs and speak from experience when I say that If there is no circulating air, it WILL get too hot/overheat.. Why not throw the chassis under the seat somewhere, and put the remote-mount faceplate wherever you want it? That is the best feature of the KG-1000G..

I ended up mounting it underneath the back seat. It is enclosed in a metal storage cabinet I have there, but there is a lot of heat transfer given it is metal and if needed I can ventilate it easily.
