Simple and easy high gain antenna ----- UHF Antenna

In the high frequency band with higher UHF TV broadcasts, the gain of the antenna is critical, whether it is transmitted or received. If the lower frequency band is not easy to make a high gain day, it is not easy, because the frequency is low, the wave grows, the size of the antenna is small, if you want to increase the gain of the antenna, the volume will increase, production Difficulties. Otherwise, because the frequency is high, the wavelength is small, the size of the antenna is also small, and the size of the high gain antenna is also very big, it is very easy to make, and almost no cost, the picture is an example, The materials used throughout the antennas are: single trough aluminum profile 46 cm, 6 square sheathed core, bamboo chopsticks, little melt adhesive. Be Be The size of the antenna is made in accordance with the 900 MHz band eight wood antennas, and the reason why the aluminum wire with an insulating layer has two reasons: First, it is convenient to fix the hot melt adhesive, the adhesiveness of the melt and aluminum is not strong; the second is the vibrator And crossbar (single tank aluminum profile) is adversely exposed. The straightening rod is purified by bamboo chopsticks to be easily and easy to bond, and the bonding method is as shown below. Be The enlarged view of the binder is as follows. Due to the small size, light weight, it is more intensive with hot melt glue, and greatly simplifies the production process. Be Be Be This antenna is not difficult, the material is easy, the gain is not low, the measurement is nearly 10dB, which is very suitable for the temporary need to solve the experiment, and it is also suitable for use as a weak television signal to receive the remote station, but at this time it should be applied Antenna amplifier. Be Be Be Be Be In addition, according to the 900 MHz band eight wood antenna size, the work frequency measurement is reduced, about 30-40MHz, is due to the diameter / length reduction of the vibrator, and pay attention to the job. In summary, this antenna is used as a TV receiving effect of 700 MHz or more, and the center frequency is near 800MHz. Many people who have used this receiving antenna are surprised. It may have the following two points for the reasons: First, this small production has been too simple, people feel that the waste is stacked, the expected value of it Not high (in fact, this antenna you is gold to make its effect, it is not going); Second, there is a lot of performance in the market in the high frequency section of TV broadcasts, and this antenna is only passive There are 10DB gains, plus the nearly 20DB gain of the amplifier, which is certainly considerable compared to its effect.
