A powered antenna will do wonders over a non amplified one. The powered ant. has a amplifier that has to be plugged into the wall to work.
The DTV Green Dish is a new antenna, partnered with a dish and forms a highly directional, high gain system. It uses the parabolic reflector to focus terrestrial signals in a similar way to satellite dishes. It is claimed to improve reception with distant transmitters and the makers suggest it will be an improvement in all situations with guaranteed reception of all major channels. Buyers should probably have that kind of guarantee in writing before committing to the antenna. After all, it is breathtakingly expensive at $300. The antenna is limited to receiving only channels that are broadcast on the terrestrial channels. Don't expect it to deliver the premium cable and satellite channels.
It helped India by building railroads, installing telegraphs and telephones and building proper hospitals and apartment blocks.
I found a slight improvement in stability by using password protection. don't know why it worked , but it did. They say you can relocate your wireless router to provide a better signal. I just purchased an ethernet cable and ran it from the wireless router to the back of the PS3 and when I checked the connectivity the speeds had increased and I stayed with a wired system since then and have never lost a connection.
First, consider an upgrade. Older monitors used 54mhz 5 watt transmitters that had limited range. Newer monitors use the 800-900 mhz band, which have better range, but can run into interference from cordless phones and other wireless devices. The simplest way to improve the range of radio frequency (RF) devices is to focus and aim the signal. Search youtube for 'cheap wifi signal booster' and you'll see dozens of tips for creating parabolic and half-cylinder shapes out of foil. These solutions are typically aimed at wifi routers, but the principle will work just as well for baby monitors. If your monitor does not have an external antenna, just place the base in front of the parabola/half cylinder and aim it in the general direction of the receiver. To get around interference or obstructions like steel framework, block walls, or foil insulation, you could chain two monitors together to get around the obstacle. By chain, I mean place the receiver of the first unit next to the base of the second unit. (This has obvious drawbacks, but it worked for us.) If you are handy and don't mind voiding your warranty, you could crack open the base unit and extend the antenna. To get the best performance, your antenna will need to be the proper length. You'll need to know the frequency (e.g. 900mhz) in order to determine the length of the antenna. The wavelength of a 900mhz signal is 33cm. Optimal antenna lengths are 1, 1/2 or 1/4 the wavelength. A practical 1/4 wave antenna for a 900mhz baby monitor would be 8.25cm. The good news is that external 900mhz antennas are common and you can buy one in the $10-$60 range. (I'd go cheap if for this project.) To get around obstructions, you can run a cable between the base and the antenna, but the more cable you use, the greater your loss of signal will be.
dont know :P
You can buy an antenna signal booster,but the reviews are not very favorable.
With 3 or more TVs you really need to add a signal booster. It will improve reception and can be added any time your antenna reception provides less than pefect picture quality no matter how many TVs are connected to an antenna.
The modern dy cell phone really has no need for an external antenna. As the number of cell towers has increased so has the signal strength.
To improve the signal :)
A quick and relatively easy way to boost FM reception is to purchase and install an FM signal amplifier; These devices normally have an on/off switch, are easy to install and come with directions. However, the best way to improve FM reception is to replace your antenna and/or car radio system entirely.
Yes, the amplified antenna will sometimes make the TV set work where a unpowered will not.
Improve the antenna.
If you want to get your favorite stations programmed in the numbered buttons on the radio, just manually tune the station then push and hold the desired button in until the sound comes back on. This adjustment is lost every time you pull the radio or disconnect the battery. If you want to improve AM reception with the stock antenna and radio, there are no user-adjustable controls.

A car antenna booster is used to 'boost' the radio waves of the car's antenna. This is usually used to improve radio quality and reduce static that might be heard.
Antenna hopping is a feature in which the Tx/Rx is passed through all the available antenna paths in a sector. No frequency is changed during antenna hopping. This helps improve performance by providing spatial diversity.
