WebAt VHF/UHF frequencies, the feedline loss can result in significantly less power applied to the antenna compared to the transmitter power. For example, transmitting 100W into 80 feet of RG-8X coax to an antenna with an SWR of 1.4:1 at 146.52 MHz will result in only 46W of actual power at the antenna. Here is an excellent coax loss calculator. WebAmphenol-Procom ha lanzado la serie ProConnect! Se trata de una innovadora antena compacta de bajo impacto visual, a la vez que de alto rendimiento y…

What are the pros and cons of having higher/lower dBi and dBm?

Effective radiated power and effective isotropic radiated power both measure the power density a radio transmitter and antenna (or other source of electromagnetic waves) radiates in a specific direction: in the direction of maximum signal strength (the "main lobe") of its radiation pattern. This apparent power is dependent on two factors: the total power output and the radiation pattern of the antenna – how much of that power is radiated in the desired direction. The latter factor is quantif… WebVol. Practical Guide to Radio-Frequency Analysis and Design. Chapter 1 Introduction to RF Principles and Components. The RF Engineer’s Guide to the Decibel. ...
