I put it together, fairly easy to assemble, and it is sturdy. they claim it wont rust outside but they gave me 3 out of the 4 nuts were steel where only the 4th nut was aluminum. It is really meant for outside, i tried it indoors near the patio door and 2nd floor window and it worked but the metal door frame/window frame probably was throwing it off. I can't comment on the range because i havnt tested it on the roof but, i have a similar antenna that i made that is only one bay without the reflector and it seems to pull in more signal bandwidth but less focused... however i did add a small vhf antenna in parellel with it so it probably pulls single better for that reason. Its maybe not as directional as i thought it would be. pointing it in the general area of the tower transmitters seems to work. im about 30km out and have 5 out of 6 bars of signal on my closest channel (13 - ckco). I plan on geting a vhf/uhf combiner to add an omni directional antenna for the vhf signals. 3 stars because it works but its not quite the impressiveness or fringe finder i was hoping for. a good omni directional would probably have worked in my area as good mounted on the roof of my home. Dont waste your time throwing it in the attic as you will probably loose 40% of your single strength. I tried it with a splitter and hooked up rabbit ears with some success but it lowered my signal on my best recieved channels (ch 13 and 28) however picked up 2 weaker channels (cbc 56, and 31 citytv) (using a cheapo splitter from princess auto). a forgiveable sacerfice in signal netted to extra channels buy adding the 2nd intenna.
Shipping killed me, would be better if i could have bought locally! Its a good deal if you think you need it. im from stratford ontario area and was kinda border line with reception when indoors. Im confident that any antenna outdoors would have perferomed as well... even rabbit ears.
bottom line: works okay but move your $25 rabbit ears outside first before purchasing with as much hieght as possible you might be surprised/satasfied with what you can bring in.
