I went to tvfool.com to find out where my sources (directions and frequencies of broadcast) for TV broadcasting in my area. You need to start there because there may be a weaker signal that is broadcasting purely vhf ranges that requires a band specific beam antenna. Here is an example. In San Diego CBS transmits from Mt. Soledad via VHF. Since that station is my problem child for reception, I'm better offer getting stellar labs vhf beam antenna specifically for that direction. Set it and forget it once up. Note: a band specific antenna will outperform a multi-band antenna. So knowing what frequency your "hard to get" tower is broadcasting is clutch information. Whereas there are several close multi band (vhf/uhf) towers in other directions that allow for this particular antenna to work well.

This particular antenna works well for three separate towers that are close by(Tijuana and 2 near Mt. Miguel). Look at the pics to appreciate how cheap the coax cable connectors are that come with the antenna. I used quad shield rg6 cable connectors instead, also pictured . A trip to the hardware store was required as another reviewer has mentioned , no fender washers and no lock washers. Paid around $15 in hardware.

I will be using a three way splitter once the VHF beam arrives tomorrow. Not all splitters are made the same. I'm using a holland splitter (ghpna-3) that will allows for multiple sources to combine into one rg6 coax to the amp before going to tv.

I haven't tried it yet, but I also orders a philips 5g filter (allows frequencies between 5- 608 and blocks out the LTE 4g/5g cellular bands in the UHF upper ranges that uhf antenna may pick up as noise). Haven't test drove the filter and the amp to know which combination will work best for me.

I also have a 40 telescoping antenna mast but will also experiment with that as there is no reason to go higher than necessary(to get the problem child -CBS broadcasts 8.1, 8.2,8.3). This particular antenna already received its intended stations 5 feet of the rooftop on preliminary tests.

My ego would love to order 2 DATBOSS antennas instead of this antenna as it makes the home look like a military communications building, but this gets the job done and receives the 3 signal in between the 2 antenna directions that a beam may exclude out.

BTW: the vhf beam is from the same manufacturer, stellar labs. build quality isn't so hot with the butterfly nuts instead of nuts that allow a socket wrench to torque down(this item will be blowing in the wind up there...), once its up the only factor I don't know about it the plastic. Are there plastics that don't substantially weaken in the UV enriched sunlight? My HAM radio antennas (10meter) that were made in the 80's are all aluminum and look fairly new. Those are holding up but they have no plastic in their construction. If it fails, then I think I'll pull the trigger on the two DATBOSS multiband beams and rename the house, the Millennium Albatross. This house will become a beacon for interstellar communication. Until then, hoping the Chinese wouldn't engineer an outdoor item with a lifespan less than 5 years.

I've read both good and bad reviews on these types of antennas (multiple manufactures; not just this one), but after installing this version, I was pleasantly surprised. I spend (or better said, wasted) money testing omni-directional models, but even with their built-in in-line amplifiers, they just didn't cut it. With this antenna however, I am now able to acquire good signals from ~75 stations that span two major locations around the town/county. I highly recommend using a high quality double-shielded RG-6 cable and a commercial grade distribution amplifier also...this will help reduce your frustration. Oh, and I also had to insert a notch filter into the signal path because our house is very close to one of those cell phone towers... you will need a filter to keep the cell tower from drowning out your antenna with unwanted energies/frequencies (between the VHF (ch 2-13) & UHF (all others above) frequency bands)

INSANELY terrible instruction enclosed !!! Photos showed the wrong way to assemble, ( showed one of the arms with a bracket attached on EACH array instead of one array with both); !!! no detail of what the would identify as "A" or "B"........ on and on! Really screwed up! Almost returned because of it
Good luck. Hopefully it will work much better than the incorrect instructions I received!

This solved my issues. I had an omni-directional amplified antenna that worked well in my attic but was not quite good enough on 1 station that I watch regularly. The stations in my area are mainly in 2 direction but about 70 degrees apart, a regular directional antenna would not work very well. This solved that issue and is still in my attic. I pointed each side of this antenna respective direction for each set of stations. Issued resolve and also picked up 2 more stations but weak. Added a preamp at the antenna and all stations I want are strong and watchable. Also have some stations that can be watched sometimes that I do not need.
I do have one issue that prevents me from giving it 5 stars. although the assembly was not very difficult, the instructiosn for assembly leave a bit to be desired. The pictures are not that useful as they are not very clear and, in the case of which side of the combiner is up, different pictures show the combiner oriented differently.
Overall, I am happy with this antenna.

I bought 4 of these, to make up into a phased stay (stacked). They are pretty easy to assemble and should have enough gain to accomplish my reception goals for receiving deep extreme fringe uhf tv signals. The harness cables included are cheap rg59, which I will replace with high quality flooded rg6 cable, the included hardware is made from steel, so there will be corrosion of the fasteners over time. Stainless steel would be a better choice for the hardware, but that would result in cost increase. I have not installed this antenna stay yet, so there will be additional review comments yet to come. I have moved to a new location that has pretty high elevation, but is farther away from the TV transmitters; so that is the reason for the upgrade. Channel master offers a comparable antenna, but it is also almost twice the cost as well. I opted for this model, so as to limit overall cost of my total MATV system. As an amateur radio operator, I am using my decades of experience with antennas to engineer my tv antenna system. I plan to include photos when I do the folow up review. For a MATV system like mine, you need a tower to support it all as windload is an huge issue. More to come. 73 and GOD bless K5EWM.
