Like stacking tribanders or monobanders for HF 10 thru 80? Or does it keep climbing up 3db? _______________________________________________ _______________________________________________ TowerTalk m

You have to double the number of antennas for each "theoretical" 3 db gain. It gets big and expensive fast and there are other factors that limit you to less than the theoretical gain. Roger (K8RI -

Also, if you are talking about vertical stacking you can actually make things worse at low take-off angles, depending on how high you can get the lower antenna(s). Take a look at this analysis on my

Well.. in free space you get a gain of N, for N antennas.. 2 antennas is 3dB, 4 antennas is 6dB, etc. And that assumes they're far enough apart vertically (on the order of 1/2 wavelength), and that g
