Worth every penny
I originally stated off with a couple yagi antennas, which worked very well. Unfortunately the tower that gave me the best signal is heavily utilized throughout the day.This antenna gives me the ability to reach out much further and “shop” for the tower with the best signal and one that is not soaked with traffic. The tower we are pointing at now is roughly 6 miles away and passes thru several tree lines as it exits our farm. Signal quality and speeds are fantastic-even though I can’t actually see the tower. Understand that it will take some time to get it pointed just right. In my case it took roughly 1.5 hours to get it aimed right. Although some of this was due to me playing around to see how far I could reach out. It’s expensive but I wouldn’t hesitate to recommend it to a buddy.

BEST ANTENNA ON THE MARKET!!! 2020
So I’ve tried 2 yagis for MIMO (WIRENG) and 2 Log periodic antennas before this. I was getting -114, now I get -103 decibels. Insanely HUGE difference on my Mofi4500. I have it up high on my roof plan on raising another 5 feet to see if that improves signal quality some. Speeds were 20-25 mbs DL and 1 UL. Now I get 30-45 MBs DL and 5-8 UL. Tip: if you are used to seeing decibels in real time you have to make slight slight movements before you see a signal with decibels or you WILL NOT get it to work. It’s laser beam technology is super sensitive and directional. So make sure you don’t give up right away. Find the best line of sight or direction toward a tower it will work! I’m about 12 miles in the sticks from tower shooting through trees. Hope this helps! Only need to get one and I have the second antenna or secondary is my Log Periodic. They work well together! Check out my reviews on YouTube! Search Parabolic Grid! Name’s John!

Low gain and flimsy construction, like walking forward with a flashlight pointing behind you
I've been a ham radio operator for over 25 years and have designed antennas but this, this is the biggest piece of junk I've ever purchased! Don't be fooled, log periodic antennas may have a tight beam width and wide bandwidth but the gain is super low and them saying it's high gain is complete crap. The gain on this antenna is so low that it struggles to pick up what a simple wire dipole can do. Considering the frequency range, one should have the phase center at around 3ghz which means over 3 GHz you run the risk of overshooting the reflector and under 3 GHz your efficiency drops; you don't get full gain across the spectrum so at 1.5ghz you would likely have 50% loss and worse at lower frequencies, assuming where the PC is. Another important factor is reflector size and angle which does not scale logarithmically to complement the resonant frequencies. That also not taking into consideration the changes in velocity factor with elements further away from the feed point since the element size is equal across the entire array (as seen in the picture). The reflector is so thin that a squirrel could fart in a nearby tree and cause this antenna to shake to the point were there is no frequency stability so don't even breath by it and don't even look at it. There are so many design flaws with this antenna that I could go on and on about the physics and design of a LPA and how this antenna misses the mark, this antenna is an abomination of physics. You'd be better off using a TP-Link 2.4ghz WiFi antenna (which is a multi-reflector dipole) or a yagi instead of this wobbly piece of junk LPA. This is in my top 3 list of worst antennas ever made! Seriously, lining an umbrella with aluminum foil would do 1,000x better than this piece of junk. I love my TP-LINK TL-ANT2424B antennas and buy them when I can because the construction is so much better and it uses a folded dipole, which can be modified for different frequencies, and has a much better feedline right out the gate. I have 3 of the TP-Link and more on the way!

Works very well
I have ATT. I live in a rural setting with the closest cell tower 4 miles away, 5 miles away, and 6.5 miles away in town. I used the weboost connect 4G signal booster with the 75 ohm yagi antennas and received signal at 2-5 mbs band 12 and band 5, could not get band 4 or band 2. Put this baby up and pointed it at the nearest cell tower and now my downloads are 40-50mbps and uploads 15-20mbps. I connected this directly to the MOFI router and got 20 mbps but connecting it to the signal booster gave me more dbi gain and allowing the booster to broadcast the signal in my home gave me another 10 dbi increase. Band 4 signal strength -50, signal quality -7 to -9, diversity signal strength -51, Band 5 signal strength same as band 4, band 12 signal strength -44, signal quality -6.5 to -8.0, diversity signal strength -46. Band 2 signal strength -77, signal quality -13, diversity signal strength -76. My DBI gain from this system set up was about 65 dbi. My mofi is locked to band 4 with carrier aggregation set to band 12 under advanced band lock. If you want great signals, make sure you lock your MOFI to two bands especially when using a wide band antenna. Do a band lock on a primary band under band lock and then advance band lock to the same band and another band preferably one with the best signal. Cheers!!

Hoping for better on 5g
I have another parabolic antenna that works great on AT&T bands 2/4. That is why I have it to penetrate the trees out where we live. I had high hopes for this one, but be it band 2, 4, 12, 17 and it does not provide the results of the older narrower range parabolic or the yagi's I have for rural internet. I'm keeping it though, in hopes that when 5g comes out here, it can help with that. For those of you on LTE, stick with the previous gen Parabolic and Yagi offerings mature on the market. UPDATE 9 JAN 2020: I have now tested this where several other modems, including modems that support Band 66 and 71. This is a highly directional unit, but once aligned it works great. It pulled in Band 71 and the results were great, tripled my upload. Its not as forgiving as the 1900 LTE parabolic, or the other Yagis though on directional aim.

Increased signal strength
There was no cell signal in my mountain home. Adding a signal booster with included Yagi antenna increased signal strength a little. Adding this parabolic Bolton antenna increased signal strength more. Signal booster has a built in signal strength meter. It ranges from negative 24 (no signal) to a positive 12 (Excellent signal). My signal strength prior to installing the booster was negative 24 (no signal). After adding the booster with included Yagi antenna, signal increased to negative 24 to a negative 7, Just enough to make a phone call, but not the best. After installing this parabolic Bolton antenna, signal strength increased up again to a negative 3. Signal is still considered poor, but it is almost in the acceptable range, according to the meter. Point is, with this parabolic antenna, I can no make reliable phone calls, send and receive. I located the cell tower, and with a compass, aimed this antenna directly at cell tower. This is considering we also have some very high hills between us and the cell tower.

Only if you already have 1 bar or better.
I have multiple rental properties in a remote valley in MT. We have tried multiple cell boosters and antennas over almost 20 years to the only tower in our valley. I'm also an old IT tech and know the data infrastructure. Will this Antenna help? Yes. If you have a decent 1 bar connect in the first place...yeah...you'll do better. 2 or 3 bars and a bit of download speed improvement...and better calls and text. If not don't bother. Obviously your results are going to be different. If you don't have squat in the first place you're not going to improve. I'll also note that I docked this 1 star because one of two antennas that I ordered showed up with 1 metal tab broken. Those tabs are used to connect the 2 halves of the antenna array. They overlap. The broken tab was not in the package leading me to think poor QC. Was able to use 3 of 4 tabs to screw it together. Not optimal but useable. Still...if you have a signal in the first place and a good solid mount antenna...worth a shot.

IT WORKS!
We have lived in a valley for the last 6 years and could not get a phone signal at all. I have tried several different antennas and boosters. Have a good Wilson booster that came with a Yagi and indoor antenna but could not get a signal. Bought this antenna, went up the hill about 60' and pointed it towards mountain with antenna on it. It is on a 8' pole we planted in the ground. Connected it to my Wilson with two gain adjustments. Adjusted the gains to solid green, connect the interior antenna after moving it around to the best signal. I went from zero bars to 5 bars and LTE service. Have not had this good a signal since cell phones were invented! This antenna is a miracle worker!

Works well
It works!!! Increased data speed from 1.5MBs to over 20MBs. Could not get any data speed increase with yagi antenna that came with cell phone booster

Good devicw
Device does work for long distance from tower. Somewhat heavier and larger than smaller units on market but works where smaller ones won't.

Depends on the cell band
Tried this as an upgrade to my cheap plastic yagi. It did pick up some higher bands (2,4) that I didn’t get at all before but not enough to actually work well. Unfortunately it didn’t improve the lower bands (13/17) much over the cheapo plastic antenna. I will be returning this and trying to find an antenna that is specifically geared for the lower bands.
