Has anybody tried this Stellar Labs 30-2475 VHF antenna yet?
It would appear that MCM is importing this item from China and selling it under that part number: http://www.qiaohua.com/products/v-9h.htm That's the same Chinese company that supplies the rest of their house brand antennas.

I'd find it pretty unlikely that it would outperform the AC Y10-13. A general rule of thumb is that antennas with similar configurations will perform in similar manners. Given that the MCM offering is short a few directors and it's a lot shorter overall, it's likely to be several dB below the AC in forward gain. The two extra reflector rods would improve the F/B ratio, but wouldn't do much for forward gain. Most likely, the Chinese company is quoting gain in dBi as opposed to the dBd that AC used. Neither MCM or the Chinese company provide that information.
