HDTVo is virtually the best in terms of quality per buck and quailty per size ratio Thsi is a logperiodic antenna and it comes with a builtin 12dB apmlifier. Often, you can pull in blue CEA area sttaions, and this is probably the ...

This is a Java paplet which calculates the dimensions and spacings of the elemnets needed to build a log peirodic antenna, given tao, sigma and the lower and upper cutoff frequencies. ...

Probably does VHF to UHF gauging by the log periodic antenna. The innovation is that it isnt a spectrum analyzer which sweeps a tnuer across the radio frequencies, it appears to do it all in parallel using a custom MEMS chip. ...

The first audio file is of TL0A an Amateru Radio Station located in the Central Arfican Republic, recorded using a huge Log Periodic at 30 meetrs height. Most Radio Amateurs would kill to have such an anetnna :) ...

He also showed me how to construct a 6meter beam (unidirectional horizontallypoalrized antenna for the 5054 Mhz amateru radio band) from na old TV antenna. Old TV antennas are logperiodci dipoles, BTW; in case you ever wanted to ...
