Bingfu low profile antenna.


Recommended Posts

So the story behind this antenna is that I actually didn’t even want it.

I was simply looking to pick up an NMO mag mount base because the antenna that I was interested in was a Melowave Shadow antenna, but don’t currently have an NMO platform for it to be on. After shopping various options everywhere I spotted this Chinese bundle of what appears to be a copy of these Shadow/Ghost style antennas. But it included the mag NMO base that I was after, for less than the price of just only the base everywhere else I looked ($25 to my door from Amazon). I pulled the trigger and figured I could just pitch the antenna part in the trash and still be ahead of the game.. 

Obviously though, being a radio nerd that I am I had to at least have a look at it. I connected it to my VNA and surprisingly it has a very nice dip across the GMRS portion. 1.3-1. I then took it for a ride checking into some repeaters in my area and got really good reports. Receive copy was great as well. Repeaters ranged from 10-26 miles away. 
 

If you read some of the user reviews online for this antenna, it’s not great. But here’s the thing about it. It’s being sold as a “ham radio, 2M/70cm dual bander”. It’s even labeled as such with a sticker right on the antenna itself. There’s no spot on VHF that is even usable for this antenna. SWR is like 6+. Even on 70cm the numbers are on the high side of the usable slope. So if you bought this antenna for those purposes, it is bad. But fortunately and luckily for GMRS users, this antenna lands resonant (by dumb luck?) at the GMRS region. 
 

This antenna is sneakily, and possibly entirely by accident, a quite good GMRS mobile antenna! 
 

Has anyone else tried one out?

My experience with a similar type I picked up cheap at a Ham swap. On the Ham 70cm band it wasn't too bad. On VHF it was VERY narrow banded to the point of being mostly useless. The SWR on GMRS put it out of the running. Oh well I got a decent magnet mount out of the deal.

I think there may have been some variations of it, but as you can see on the VNA, this model lands nicely into GMRS. I’ve been talking on it very reliably and getting good reports.
