Universal Antenna Bilbotc2 4 weeks, 1 day ago
If by "universal" you mean an antenna that will work well on 160 through 6 meters, I'm afraid there is no such beast. A multi-element beam (Yagi or log periodic) provides the highest gain, but such antennas are generally only practical on 20 meters and higher. The usual compromise is to have one or more beams that cover 20M and up, and one or more wire antennas (dipole/doublet/loop/sloper) for 30M and below.

And of course, if you intend to operate VHF and UHF, that will require a separate antenna.

best radio on market today SQJUMPER 4 weeks, 1 day ago
There is no "best" radio for all situations, and other than saying that you want an all-band radio (HF/VHF/UHF) you haven't given us much to work with.

Which modes do you like to use (voice/CW/digital)? Do you enjoy contesting, or are you primarily a ragchewer? Do you plan to chase DX? Do you operate primarily from a fixed location? Do you plan to do any portable operating? Do you want to be able to take the radio with you on vacation? What is your budget? Do you want to buy new equipment or are you willing to buy a used radio?

serial numbers leroy271 on 19/10/15
A serial number is simply a unique number that is used to identify a QSO. Usually, your first QSO is 1, the next one is 2, etc.

I ran my coax through the end of the ridge vent on my roof, into my attic. My shack is on the second floor, though. This isn't a good solution if your shack is in the basement!

SLA (sealed lead-acid) batteries come in many different sizes, are relatively inexpensive, but very heavy. LiFePO4 (lithium iron-phosphate) batteries have a much higher energy density and have a longer life than SLA batteries, but cost more. As Zack states, you don't need to worry about surges, but batteries contain a lot of energy and a short-circuit can have catastrophic consequences. Fuse your power lines and be extra careful with any exposed leads or connections!
