![]() ![]() ![]() Here is a link to my 2.4GHz 18dB panel antenna with polar traces…Īnd here is one to a 2.4GHz 18dB Yagi antenna with polar traces… Tell you that they can fly a mile behind their Yagi and they mount While a patch sitting on the ground can almost act as an omni. You generally can't fly very far to the side or behind a Yagi, The most practical difference though is that Yagis just almost always haveĪ much narrower beam width (thus their higher gain) and it's very one sided in theįorward direction. That's why I use diversity with one on a tripod and the other on the ground. Having it high enough to get clear LoS, but low enough to get highest gain. With patches it's often a balance between Mount a Yagi on a high tripod to get over ground clutter (grass/bushes etc)Īnd know you're getting the full gain. Long, but otherwise is pretty light, and of course very easy to aim exactly whereīut assuming they did have equal gain, one benefit to a Yagi is that,Īt least in the lower frequency bands (like 900Mhz and 1.3Ghz) they don't needĪn external ground plane to be maximally efficient, while often the patchĪntenna works best quite close to the physical ground. Usually ends up being quite large and heavy. Than a patch is capable of when you get up over about 9dB. The usual benefit of a Yagi is that it provides much higher gain Well, generally it'd be pretty pointless to choose a Yagi with identical gain ![]()
