Why did you pick this product vs others?:Right out of the box this antenna has evidence of previous assembly, specifically scratches on the aluminum from screws being installed. While assembling it, a good amount of screws would not tighten properly, leaving connections at the beams loose which is unacceptable. Its apparent this seller sold me a used item that probably had been returned due to screws probably being over tightened during assembly. In the instructions it specifically states to refrain from re-assembly due to this exact problem, which was an issue right out of the box, due to them selling me an antenna that has obvious evidence of previous assembly. The return process is a pain, why would i go through more time & trouble than its worth, when they will probably just resell this antenna again.I am going to have to do the labor to fix these attachment points which isn't a huge deal, but at this price is unacceptable to have to go through. should have a more sturdy assembly process instead of pre drilled holes and self tapping screw to secure this thing together. id give negative 5 stars if possible.

This antwnna was easy to assemble and deploy. I am using it to track weather sondes at the low end of its usable frequency range with a measured VSWR of 1:1.12 @ 404.8 MHz. In the vertical polerization attitude, it affords me at least a 10 dB gain over the UHF monopoly previously used. Time will tell if it can withstand coastal weather patterns and wind. It is deployed 18 miles from the Gulf of America coast, so the conditions are often high humidity and windy. I have purchased 3 of this antenna now and they are spread around Texas from the coast to North Tx.

I needed more signal strength to punch through the trees around my house to connect to a GMRS repeater 13 miles away. Using a nanoVNA, I tuned the antenna to the GMRS frequency band, and with the VNA connected directly to the antenna had an SWR reading of 1.4 to 1.6:1, sweeping from 462 to 468 MHz. Installed the antenna on a 10-foot length of 1-inch PVC electrical conduit, and connected to the radio (15 watt output) with a 43-foot length of DXE-400MAX (LMR-400 equivalent). Final SWR check is equal to or less than 1.1:1 (!). Using LMR-600 has lower loss at UHF frequencies, but the cost of buying a connector crimping tool for one job is prohibitive; I have the tooling for DXE/LMR-400.

Initial review:Antenna is easy to build, easy to tune. Kind of a mid quality item. I wonder how water proof it is, we'll see how long it lasts in the weather.I'll update after I use this for a while.Update: I've been listening around the channels and have heard stores that use FRS walkie-talkies four miles away from me. It definitely will cover the neighborhood.

This is a good antenna, not great. It works for around town but not much more. I would buy again because I think the price is good for what you get.

This is a great Yagi, power handling and frequency range are perfict for many ham radio projects such as links or base to repeater applications.The only week point that I see, is the small screws to hold the elements to the boom. If you have rivets available, I would use them insted of the small screws.Other than that, it's a great product for home use!

I bought this antenna to use as a Vertical to use with a 433mhz Gate Opener. I needed to boost the 433 signal that was limited to 800 feet Line of Sight under power lines. Metal in close proximity (such as a metal mast does affect the tuning To tune there is an adjustible block that induces signal onto the radiator .If you mount the block at the end of the shrink tubing it will be near 433mhz and be quite low to 425mhz.the best way to fine tune is in-situ mounted on a 1.5 inch PVC Mast at the height you'd like to use.then use a tuner to adjust the tuning block. I suggest building the antenna on you kitchen table.This antenna has 2 tiny set screws and 3 Phillips screws to secure the aluminum Reflector, Director and Radiator Elements to the Square frame. Make sure the Screws are tight keeping the Radials tight. There should be no movement of any parts of this antenna. The instructions are good. It has a potential Gain of 9 decibels. a 3 decibel gain doubles the signal size. The Vertical Beam With is 45 degrees which is excellent - Not too narrow. If tuning is critical you will accomplish 1.4 SWR but you will need to tune IN-SITU with the cable employed for you use. 50 ohm cable is best. RG-6 will work but the SWR may be higher. Point the Antenna in the transmitter direction and secure to mast before testing. The use of a Comet or other antenna analyzer 433mhz capable meter is suggested for the most accuracy.If the gain is not enough , consider the 11DB Gain version of this antenna. This antenna will Transmit and Receive with most Remote 433mhz Remote Control, 70cm Ham Radio, GRMS and Weather Radio.Receivers 400-470mhz See specs for details.
