- 27/04/2010 · Just about all the VHF/UHF TV Yagi antennas are like that. Some examples: < writesOnly a 'transformer' splitter can have a through-loss of 3dB. Actually, it is theoretically 'lossless'. The 3dB loss isn't a loss at all. It's 3dB because the power is split into two equal paths. In practice, there is some real through loss - typically 0.5dB at 50MHz, rising to over 1.5dB at 900MHz, so the
