Ultra-Thin Indoor HDTV Antenna

There is no one magic antenna or antenna type that will deliver excellent TV reception in every
location. The main factors determining reception are the distance and direction from the TV
station transmitters to your home. Other factors include the transmitter's power and the height of
its tower, the terrain between the tower and your antenna, and the size and location of any large
buildings in the path of the transmission.
If you live within a few miles of the transmitter, and the signal path is relatively unobstructed,
you may be able to get adequate reception using a small set-top indoor antenna. But as you move
farther away, getting usable signal strength becomes trickier. This is where careful antenna
selection and installation become essential.
The information below will help you zero in on the type(s) of antenna that should work best for
you. Keep in mind that even in the same neighborhood reception conditions often vary from
house to house. For that reason, it's best to purchase your antenna from a dealer who offers no hassle returns with a money-back guarantee.


One of the good product recommend by customer reviews is Ultra Thin Indoor HDTV Antenna from AmazonBasics. These antennas coming with 4 types of model and range, from 25 Mile, 35 Mile, 50 Mile and 60 Mile. With 1 year limited warranty.  One of customer get almost 44 Digital Antenna channels found. This antenna for 50 miles range will worth your time and effort

Wi-Fi 2.4 GHz Antenna

The Speed of your wireless connection will vary depending on the strength of the signal you can receive and transmit. Antenna selection can therefore have a significant impact on the speed of your wireless link.

Types of Wi-Fi Antennas 

 There are two basic types of antennas for WLAN and cellular products :

Omnidirectional and directional. The two types are categorized by the direction in which they beam radio signals.

Omni-directional

Omnidirectional Antenna Pattern

Omni-directional antennas are designed to radiate signals equally in all directions. Use this type of antenna if you need to transmit from a central node, such as an access point, to users scattered all around the area. Omnidirectional antenna consist of 2,
Dipole antenna, and

Directional Antennas

 

Directional Antenna Pattern

TPLink Directional Wi-Fi Antenna

Directional antennas provide a more focused signal than omnidirectional antennas. Signals are typically transmitted in an ovalshaped pattern with a beam width of only a few degrees. With higher gain, directional antennas can also be used outdoors to extend point-to-point links over a longer transmission distance, or to form a point-to-multipoint network.

Antenna Connectors

N Type Female Connector

PRSMA Connector

MCX Connector

Before you purchase an antenna for your wireless device, you should check the type of antenna connector that your device uses. You will need to buy an antenna with a matching connector. There are several types of antenna connectors, including MCX, TNC, N-type, SMA, and RP-SMA (RP stands for “reverse polarity” or “reverse ping”). On WLAN devices, the most commonly used antenna connector is PRSMA and N-type for IEEE 802.11 wireless applications. Make sure you are buying an antenna with the right connector type.

What Negative Comment from Users about This Products ?

Some users convince that this antenna won't work for people who have their TV very fair away from windows. Because the length of the cables on the antenna are simply going to be too short for most people.  If your TV isn't within 2-3 feet of a window facing in the optimum direction, this won't work very well, if at all, for you.

The other major problem is that the suction mount for the antenna is pretty much worthless. It stuck on my window for approximately 15 seconds before falling off.

The antenna does work but you need to really be facing the right direction which can only be determined by trying it out. And the mount is really poor plus the short cables make it mostly unworkable for most people.

Another customer give negative comment about this antenna , "this antenna makes me really disappointed, also the amplifier makes the reception worse than better for most channels. My home is only 6 miles north from Seattle's downtown, using antenna only I can not get local channel 22, 33, 42, etc.; using "antenna + amplifier" I can get sort of reception on channel 22, but the same time worse reception on other channels."
Another customer said that this antenna  "It did not work. It did not increase my signal strength so I returned it "

Simple Transistor Tester with mA meter as Indicator

This Transistor circuit Tester use for testing whether your transistor it still in good condition or not. This circuit of transistor tester using mA meter as an Indicator.

This Transistor Tester use for check whether the transistor tested in good condition or not. If the transistor tested still in good condition, mA meter pin will move , if the transistor tested not in good condition mA meter will not move or steady.
Switch S1 and S2, is sliding switch for setting whether the transistor tested is NPN or PNP.

S3 is sliding switch for set capacity power of mA, in this circuit we use 1 mA meter.
S4 is Push On Switch for giving voltage current to tested transistor.

When we want to tested NPN Transistor, Switch S1 and S2 we connect to Q2 and Q4, and press Push On Switch S4 to test the transistor . If the transistor in Good condition, the pin of mA meter will move to on a number of measurement. If the transistor in not works well , the pin of mA meter will not move .
