Had a call from a customer the other day, saying a competitor’s cellular Yagi antenna was no good, even though they claim it is very high gain. As Siretta offer a number of good quality Yagi antennas, I thought this would be a sale opportunity. Asked few more questions only to find out he had installed his antenna facing the building. Explained Yagi antennas are good but not that good and he should really install his antenna in as clear a line of sight to the base station as possible to get a good result. A couple of days later he called back thanking me. It seems I can spot a good sales opportunity but not the sales.
Anyhow, the question of whether to use a Yagi or an omnidirectional antenna is a valid one.
