Will I Need an HDTV Antenna For My HDTV?

!±8± Will I Need an HDTV Antenna For My HDTV?

With the growing interest in HDTV and digital TV, there are lots of merchants trying to tell people that they need to buy a new antenna when they buy a new TV. This is not necessarily true, because there is no such thing as an HDTV antenna or even a digital antenna. An antenna is essentially just a piece of wire, and it can't tell the difference between a digital and analog broadcast. What really matters is whether you have a digital or analog tuner between the antenna and the TV, or integrated into the TV itself.

But, you do need to have a certain kind of antenna to watch a digital broadcast, as things stand today. You are probably familiar with the difference between VHF (channels 2-13) and UHF (channels 14-83). Right now, the vast majority of TV stations broadcasting in digital are using the UHF range, so the solution to the digital/analog question is very simple: just get a UHF antenna, or a combination VHF/UHF antenna. Fortunately, almost every antenna available does receive UHF signals, so this is really a non-issue.

It's pretty likely that TV stations will eventually start to use the VHF range for digital broadcasts, since there is no technical reason not to, but no one knows for sure yet. So, your best bet is to get a UHF antenna for all digital TV and HDTV broadcasts. If you want to watch local analog broadcasts between now and February 2009 (the date of the analog to digital switch), get one that also does VHF.

Even though antennas aren't fundamentally designed to receive digital or analog broadcasts, the whole world of TV broadcasting is going digital, so manufacturers are starting to design antennas to fit better into the digital world. Using an antenna from the digital age with your digital TV makes the whole experience a little more user-friendly. So, if you are buying a new HDTV, you sort of need to buy a new antenna, but not really. For more information on antennas and HDTV in general, check out a helpful HDTV info website.

Maintenance Tips and Restringing Weed Eaters

!±8± Maintenance Tips and Restringing Weed Eaters

In landscape industries and in homes, weed eaters are very important. They are needed to reduce or remove weeds. Weed eaters are made of aluminum or steel bars with a motor and blade or nylon string on two different ends. There are weed eater models with two handles. Others are just comprised of a single handle.
 
Weed eaters needs very little maintenance. It should only be kept clean all the time. Dust it off with dirt, grass or weeds that clog the head. An air blower or compressor will help remove these unwanted elements. But without this accessory, cleaning is as good as doing it manually. You can use pointed objects to remove dirt in the littlest corners.

For weed eaters that use strings, it will be kept in tiptop shape if you replace the strings regularly. Normally, strings are replaced once it becomes thinner and looks like it is about to break off. But for better maintenance, you can set a regular period for replacing, say once a month or once in two months.

Thread the string properly while making sure that the string you use is of adequate length - not too long and not too short. The string should not scrape with the plastic cover which goes around the string. It your weed eater has a roll hooked, you just simply have to press the head and pull the string once the string thins out. Continue pulling the string until you get the right length.
 
Be sure that all the gadgets you need are ready before you start trimming. Prepare all the extra strings that you need and also the blades ahead of time. If you have a gas power weed eater, have an extra gas on the container. If it is electric, have a longer extension cord for use.
 
For rethreading, it is a fairly easy process. All you have to do is buy a new spool of plastic line. Use this to replace the old one, pull out a bit of it so that it sticks out past its opening - two inches is enough. After this, snap the new spool in and your weed eater is ready to move.
 
When talking about the string of the weed eater, for non commercial models its diameters ranges from 0.065 to 0.095 inches. But to be sure of the size, follow the recommendation in the user's manual. Weed eater's string should be well maintained. When you noticed that the string is already low, remove the lower part of the head by removing the lower part; push it slightly then turn clockwise. Cut the new string. It should not be shorter than 6 inches, otherwise, your weed eater will not advance its string properly when used.
 
Be sure to thread the string back following the guides properly. If you do not put it the right way, there is a possibility that the head will pop off during use. After that replace bottom of the head - push and turn it clockwise. An easier option is to just buy the string replacement cartridge. Although this is more expensive, it saves a lot of time, and also eliminates the hassle of stringing the machine yourself.
