amp on a ht Barre1951 5 days, 19 hours ago
Hi. You can use an amp with an HT. I have one that I got in a trade. Its 5 watts in, 40 watts out, FM mode only. I don't know how much these cost. It is probably a better option to get a mobile radio for your vehicle.

Hi. Whether you want a dual band radio will depend on 70cm activity in your area of operation. While there is one 70cm repeater local to me there is very seldome any activity on it. Being a Kenwood fan, I would recommend the TM281. You will see very little (if any) difference between 65 and 75 watts output.

Hi. Bill is right. Nothing can reliably protect your station from a direct lightning strike. I can't quote the exact numbers, but if all of the energy of an average lightning strike could be captured, it could power everything in Los Angeles for a year or more!

Power Strips KV5WS on 14/5/13
Hi Guys. The best power protection will be provided by quality UPSs. Thats Uninteruptable Power Supply. They are kinda expensive, and are designed to to be used wit computers and other sensitive equipment. They have a battery that will power the device(s) connected to them for a few minutes, long enought to properly shut down a computer.

Definetly avoid cheap outlet strips, and the cheapest UPSs too. Outlet strips are handy in older houses or situations where you need more outlets than you have. Most outlet strips are rated at 15 Amps, so be carefull not to overload them.
Antenna Wire Size W0RPS on 11/5/13
Hi. I would recommend #18 CopperWeld wire. This is steel wire with a heavy copper coating. It is stronger than plain copper. I use it for an 80m dipole here. Squirels (locally known as tree rats!) caused my old dipole to break at least once a year. The only problem is that the CopperWeld is stiffer and you cannot allow it to kink or it will cause a weak point that can break.

My antenna is pretty hard to see, and I know where to look. Many people seldom look up anyway.
