In modern day city environments, it is important to install a low noise Yagi to ensure you have the best chance of receiving weak signals. Many factors ensure the low noise properties of a Yagi are maintained and as well as pattern achieved through modelling, a closed loop feed system is important too as this installs a band pass filter property to the antenna as well as offering protection to the transceiver from adverse weather conditions such as lightening and static build up.
Neil G0GGG installed one of the latest third generation LFA Yagis this year (LFA-3) and in 24 hours secured weak signal contacts all over Europe, Japan and North America.
