Hace 4 días · La ganancia de la antena es esencial para: Maximizar el alcance de la comunicación: Las antenas de alta ganancia pueden transmitir y recibir señales a mayores distancias. Reducir los requisitos de potencia: Al enfocar la energía de manera más eficiente, se necesita menos potencia para la transmisión.
Hace 3 días · Most times it means putting your antenna up as high as possible. As a long standing rule of thumb: If you double the height of your antenna you will gain 6 db gain! That means if you had an antenna at 25 feet and decided to put it up on a small tower to 50 feet of height, you'll gain 6 db! That is ALOT.
Our selection of antennas handles from 10 watts to 350 watts of power and covers a wide range of frequencies. We offer VHF mobile and UHF mobile antennas of all sizes and gain figures. Find your VHF/UHF mobile vertical antenna at DX Engineering today.

Hace 1 día · Calculation Formula. The G/T ratio is calculated using the formula: \ [ \text {G/T Ratio (dB/K)} = G - 10 \log_ {10} (T) \] Where: \ (G\) is the antenna gain in decibels (dB). \ (T\) is the system noise temperature in Kelvin (K). Example Calculation. For an antenna with a gain of 38 dB and a system noise temperature of 65,000 K:
Hace 2 días · The proposed antenna is designed to exhibit an optimal radiation characteristic of around 8.2 GHz with a CP antenna gain greater than 16 dB and similarly wide impedance and AR bandwidths. Experiments with the fabricated CP antenna were performed to support the proposed CP antenna design theory and are in good agreement with the simulation results.
