Understanding Gain aka db
I am currently veiwing the new digital signal with a antenna that has a average gain of 7.2 db. Because I dont have LOS with the transmitting tower I guess I am veiwing most/all my digital signals from refraction from the clouds. currently my area is under a high pressure ridge aka no clouds in the sky and I am getting signal interuption or no signal messages. I am currently looking for a new antenna and there are so many styles/shapes and sizes that its very frustrating to choose witch one to purchase... one is a 8 bay or bow tie antenna that says it has a gain of 15.8db and the other is a Yagi style and is a bit smaller in size but says its gain is 28db. I'm just guessing but I would think the higher the gain the better the reception would be ?... but if I dont have any signal to recieve I could have a 100db gain antenna and still not receive anything ..Right ?
