What size AMP fuse?

[ousooner]

Okay for most of you out there this will be simple because most of you really know your systems. But, I do not so I need your help. I have installed a basic Galaxy DX 959 (straight out of the box , it was "tuned" by the supplier; however, I am not seeing any increase in wattage on my meter) I installed the radio in my F-150. I ran the power line to the vehicle's battery. I installed an in-line fuse approximately 6 inches from the battery. What size AMP do I use? ( I am currently using a 20 AMP fuse) I am running a standard radio, battery and altenator, (I would like to increase the entire system later but for right now everything is standard). Also the fuse holder that comes atteched to the radio the white plastic fuse holder / housing which is usually located approximately a foot away from the radio. That white plastic housing broke. (actually the smaller cap cracked) I went to Radio Shack to buy a new one. But they did not have one the size I needed. The power and ground wires on the radio are 12 gauge the fuse housing / holder in Radio Shack was about 18 gauge. So I installed another in-line fuse and I am currently using a 2 AMP mini fuse is this two high. Everything is working fine now but I can not afford to buy a new radio.

The truck is a 1989 Ford F-150 XLT Lariat. I am using two 102" SS whip antennas. Each antenna is run on a separate coxial feed line connected to a switch which allowes me to chose which antenna I want to run, (I cannot run both antennas at the same time). I have one antenna mounted on the truck roof dead center, and the second antenna mounted on the left rear pannel just above the gas tank doors, (not directly over the gas tank doors).

So what size fuses do I use? Thanks

Hi ousooner

Get rid of the 20 amp fuse. You might as well be using a nail. No more than 3 to 4 amps on the DX 959 when using SSB. It comes with a 2 amp, but after peaking it may need a 3 amp; no more than 4 tops!!

Good Luck
