I'm going to be in the market for a 2m/70cm antenna soon and need help with the gain ratings. (I am currently considering the Cushcraft ARX 270, input/experiences about this or others would be appreciated.)
Some companies list the gain in dB, while others use dBd or dBi. From my limited research, it appears that an antenna rated at 8 dBi is around 6 dB.
Could someone post the differences in these measurement techniques?
Is dB the more accurate and/or standard measurement? Is there a conversion for dBd and dBi to dB or vice versa? I would like to compare antenna's on an even playing field.
