I’m trying to decide between the Antop 400BV and the 415B. I use an attic mounted 30+ year old Yagi and I previously tried a ClearStream 4V. Both provide very similar and very good but not perfect reception. I’m using a 40ft quad-shield RG6 cable and the signal is not amplified and I get 27 Db S/N on all stations except 23 Db on 41.x. I have a mix of UHF and VHF-HI stations and my ZIP is 55346 and the various antenna locators show I have a 48 degree spread between the antennas. My major network stations are near perfect but 41.x and 33.x are sometimes problematic. Will the multi-directional 400BV handle the 48 degree spread or should I opt for the omni directional 415B? If I forget about the 41.x channels (ION), my spread is a miniscule 4 degrees. Here is the antenna information for my area:
https://www.antennaweb.org/Stations?Address=Eden%20Prairie%2C%20Minnesota%2055346%2C%20United%20States&AntennaHeight=True&Latitude=44.87&Longitude=-93.49
This is from the Antop Support website (page downward):
Q: What is the coverage angle/degrees for the 400 bv big boy?
A: 120° is the best reception Coverage degrees for AT-400BV.
@yardbird uses it with a 45 degree spread (if I recall correctly).
I also had the ClearStream 4. It’s a great antenna but the beam width wasn’t wide enough for my 45 degree spread. Stations at one end of that spread are almost 40 miles out. Stations at the other end of that spread are only 8 miles out.
Switched to the Antop 400BV and no longer have any issues with stations being on the edge of beam width. The Antop has a much wider beam.
I wouldn’t use an omnidirectional antenna. And depending on how important those Ion stations are to you, a 4 degree spread is nothing and you could stay with a very narrow beam Yagi. Otherwise, I’d be pretty confident that the Antop 400BV will pull those 41.x stations.
The 400 BV will be delivered Wednesday. A gift of your favorite adult beverage to anybody willing to go up in my attic and install/tune it this weekend 
Thanks for the info and advice.
I’d fly to Minnesota but I’m allergic to snow 
Lol it’s mid 70s and we are having a thunderstorm right now.
But knowing our weather I can’t rule out snow for the weekend 
Montana got snow!!!
NewEgg has the 400 refurbished at $56 and 400B refurbished at $60 right now.
The confusion about whether “VHF-Lo” is covered on Amazon is likely because the 400BV with the two added rods DOES cover that frequency band. Without the “V”, not. See detailed specs for both on the AntopUSA.com websire. Mine gets our local channel 7 just fine, but of course that is “VHF-Hi”. It is moving during repack phase 9 to a UHF channel, so it is the only VHF station left in the Charleston metro area - until around June.
First time I’ve seen Refurbs on Antop product. Great opportunities there.
Exactly why I mentioned it here. I was considering their AT500SBS model until I found these yesterday and now I have an AT-400B on the way, scheduled for delivery on Monday. It has their smartpass signal booster and I also already bought their smartboost (advanced plus two coax out feeds. I should be set! It looks like an awesome antenna for our specific needs and generally seems to have a great rep amongst cord cutters.
Does anybody have the VHF bars they don’t need? We have only one VHF-Hi station left and it moves to RF channel 24 in May or June (repack part 10) but there is one weak station broadcasting on 12 that I would like to try to get.
Before when I looked at Amazon.com the AT-400B was at least $80 even used “Good” condition, but right now I see several “Very good” or “Like New” for around $55-$57. It seems there are 3 or 4 listings for that model, try here: https://www.amazon.com/ANTOP-Multi-Directional-Tools-Free-Installation-Performance/dp/B01LSPKWUS
Guys and gals: what’s the difference between the 400 and 800 models? They appear to be the same and size is identical. Of course the AT-400 comes with the Smartpass amp and the 800 comes with the “SBS” Smart Boost Signal amplifier. Other than that? A side by side comparison of the specs shows identical size, weight and all given specifications.

I have the 400BV the one with VHF arms and it works great. If you have any VHF channels in your market get the BV variant.
No question about it being the optimal solution especially for Tablo users. I already have an AT-400B and wanted to play around with a channel 12 here (both real & virtual 12, so VHF-Hi). I never saw it before and I don’t get a good enough signal to use it, but I would like to add those 12 subchannels (12.1 - 12.12) to my Tablo.
Channel 7 - also VHF-Hi - comes in well enough, but it is only 10 miles away. 12 is in the exact same direction, but 22 miles.
My Antop is pulling most of our stations from 38 miles and I do have some trees in the way.
I’m in a 4th floor apartment and have yet to find the perfect solution with an indoor antenna, but hands down the Antop 800 is the best I’ve ever had. After a lot of experimentation I’ve got it angled in a corner with one rod removed and the amp turned down a bit. By far the most consistent antenna I’ve come across.
One of the things I like about the 800 series, is that it comes with a pedestal for indoor use, and looks great as well. Before installing an antenna on my rooftop, I used my 800 in the living room. Pulled in all the stations I needed at the time.
The Antop 400-BV also comes with a pedestal.
We used ours indoors for months before my wife noticed she couldn’t use our turntable. 
What’s a turntable? 
It’s what the cool kids are buying nowadays. (suddenly the whole Tide-pod thing is making sense)
File that one under “irreconcilable differences” … and a smart wife!
