40m 2el Yagi linear load
This 40m yagi, which shows very high performance on our tests, isn't ispired from any other model. Lots of yagi models are analyzed and this model figured out. The most spesific part of this model is having belove 1:5 SWR value and 175 khz bandwith

4 element 14 mhz yagi for 7 MHz
This article is about how to turn a CueDee 4-element monobander for 14 MHz into an efficient duo band for 7 and 14 MHz with some ingenious handles.
2 elementi Yagi per la banda 40
Mi son deciso di scrivere delle note tecniche e costruttive della 2 elementi Yagi per la banda 40 metri home made OB2-40
Linear Loaded 40m Dipole
Here is my dipole for 40m band. It is a simple linear loaded dipole feeded with 450-Ohm openwire feedline
