FM Dipole Omni-directional Antennas
The dipole is the simplest type of antenna from a theoretical point of view. Most commonly it consists of two conductors of equal length oriented end-to-end with the feedline connected between them. Dipoles are frequently used as resonant antennas. If the feedpoint of such an antenna is shorted, then Dipole Antenna will be able to resonate at a particular frequency, just like a guitar string that is plucked. Using the antenna at around that frequency is advantageous in terms of feedpoint impedance (and thus standing wave ratio), so its length is determined by the intended wavelength (or frequency) of operation. The most commonly used is the center-fed half-wave dipole which is just under a half-wavelength long. The radiation pattern of the half-wave dipole is maximum perpendicular to the conductor, falling to zero in the axial direction, thus implementing an omnidirectional antenna if installed vertically, or (more commonly) a weakly directional antenna if horizontal.

A: We are a transmitter manufacturer located in Anshan, Liaoning, China.
Q2: I am very interested in your product, can you send me your full catalog and price list?
A:We can select some popular products for you immediately. Please let us know your requirements so that we can send the quotation to you.
Q3: What's the payment method you accept?
A:30% deposit T/T in advance, the 70% balance must be paid before the delivery normally,about special condition, we can discuss and solve it.
Q4. What are these equipments used for?
A. We are original manufacturer in FM Radio & TV Broadcasting equipments; they are professional used for FM Radio & TV Broadcasting Station (Transmitting equipments.)
Q5. What equipment & solution does your company can provide?
A. We can do complete solution for FM Radio Station System. It includes:Studio--Link--Transmitter--Cables--Antenna.
We also can provide complete Transmitting part of TV Station. It includes:Link—Transmitter—Cables—Antenna.
Q6. How large areas can One Station cover?
A. One FM or TV Station can cover one city or one town.
The Maximum cover ranges of one station can not exceed 100KM Radius because the Earth is Curve.
You can use multiple Stations and different frequency to cover larger area.
Q7. How do I choose suitable equipments for my station?
A. The most import factors are power and frequency.
We need to know the power and frequency you need exactly.
What's the distance do you want to cover in Radius?
What's the height can your antenna can be installed?
Q8. How to calculate the cover range of the broadcasting equipments?
A. The cover range depends on 4 factors:
1. Power from transmitter; 2. The height of antenna; 3. Gain from antenna; 4. Environment around.
Then we can know the cover range of your station.
Q9. Is the Frequency Adjustable?
A. FM Radio Band Frequency is 87~108MHz, TV Band Frequency includes UHF/VHF band.
For FM Radio Transmitter; Power Below 2KW is all adjustable. Above 2KW would be narrow.
For TV Transmitter; all Frequency Band is very Narrow, only can contain around 3 Channels; so it’s not adjustable.
Q10. Is it available for your analog TV transmitter to be upgraded to digital?
A. Yes. But the frequency bands should be the same.
The only difference between analog and digital TV transmitter is its TV modulator.
After upgraded to digital, the power from TV transmitter reduced 5 times.
For example: 1KW analog TV transmitter can be upgraded to 200W digital TV Transmitter.
Q11. How to do installation of these equipments?
A. For small power station, the equipments are very easy for installation.
For large power station, we can send our engineer to your country to help you do the installation, but you should pay the cost.
