I go the chance to take one of these apart this afternoon.

In case you were wondering, here's what's laminated inside the antenna:



The balun connection didn't survive the dis-assembly (it's just soldered to aluminum foil), but the balun is a surface mounted ferrite core, wound-wire balun. Nice and compact, but otherwise pretty conventional.

I'd equate this roughly to our basic Micron or C1 loop in terms of gain and reception pattern. Like our loop antennas, it would benefit from a reflector as previously suggested. It certainly isn't omnidirectional as I was able observe on the spectrum analyzer.



Have fun!

Surprised that gets anything in with only 5 inch elements.

Hmmm...

So now we know what all the hype has been about. It's been about the hype!

Thanks for showing the construction of the Leaf.

I live 40 miles northwest of Chicago, about 40 miles east of Rockford, IL. I bought Mohu Utimate ($89.95) and I do not think it was worth the money, When I first bought it , it was great. It brought in the signal from channel 2 which I had never received atall , ever, on H-D TV. As time went its perfomance diminished. I no longer receive channel 2 and many of the other channels are as uncertain and as sporadic as they were before I started using the Mohu Ultimate. The picture &/or sound freezes and then the screen goes blank, the picture will pixilate and then go blank. The antenna often or usually needs to be repositioned when changing channels and then go throughanother channel search process
I think that a $90 antenna could at least have a base, a pedestal, a tripod, something you place on a table, etc. that you can rotate slightly or move slightly. Taping it to the wall or window is just a bad idea and doesn't work well. I wonder if taping , untaping , retaping and repositioning the antenna was causing the antenna to lose its effectiveness,
A fine antenna , but does not live up to the claims of the manufaturer.
Excuse me. I have to do something with my television; the screen is going black again and again and again and again.

I have one of these in Sparks NV..a little under 30 mi from the transmitters in hilly
country. I am in a ground floor apartment.

I can receive those channels VHF13 and above but not those on VHF 7 & 8.
Tried it both with and without the amplifier. Actually it's better than I had expected.

The next step is to try it in another location.

The similar Winegard Flatwave normally has better VHF capability than the Mohu Leaf. Sears sells the amplified version under the Alphaline brand, but the Winegard amped version at Costco is cheaper. Also Home Depot has the unamped version. But a Terk HDTVa or HDTVi may be a better choice for indoor antenna, especially for VHF with the rabbit ears. Sold at Fry's and HHG.

Sparks, NV (89436)

I have a previously installed FM twin-lead dipole antenna.. so I bridged to that with a 300/72 balun and used a backward splitter to
combine the signal with that from the Leaf. The result is that I get all the locally transmitted stations except PBS (no loss there)!

I may try putting the amplifier somewhere in the circuit to see if PBS (ch15 / PSIP 5) comes in, but their transmitter is on a different mountain
and may be lower power.

I happened upon this old thread while searching to see what might be posted about Mohu's New Channels Tuner, WiFi, Bluetooth Remote Keyboard, Air Mouse, Remote with apps.

I cut my Cable in 2013 (was Comcast and predecessors until 2010 and then Prism, Much Better) and never looked back.

I have two Mohu Leaf 50's (think they're called "Ultimate" now).
Here is my 'TV Fool' report for my address:
http://www.tvfool.com/?option=com_wr...8e03a4ae55ed9c

First one was tried on East wall (Vaulted Ceiling sloping up 16') and since I have frame construction above 10' with stucco over metal mesh as outer wall, it only worked in a window. I also have a Metal Roof, so an attic Antenna is not an option.

I moved it outside and high on the wall that is aligned 010/190 true and it worked great, spent a long time moving it and was surprised what a few inches did.

I then permenantly bonded and sealed it and its cable to the wall and finished with paint so it's nearly invisible.

While at it I placed an XM (SkyFi) magnetic antenna near top of the roof that slopes down facing 190 true, this works great and finally bonded an FM 18" Circle Antenna to the peak.

I get perfect reception on all the TV Fool 'green' channels and secondaries. I am using the newer Mohu USB Amp to feed through the Panasonic DVD Recorder and on to the Samsung TV and a Channel Master DVR+ through a good quality splitter.

Second Mohu is inside, 10' up on top of a stub wall in a central part of the house feeding a Sony and a small RCA. This also provides excellent reception. Mohu is a fine company of Veterans and I am completely satisfied with their Support and Products.

In my particular location, I can't imagine a better antenna than the Mohu. TV Fool lists a lot of "2Edge" and "Tropo" stations and it's true that sometimes I can do a Scan and get Tampa and West Palm Beach stations a 100 miles away, but they're usually same Networks as the Locals and will be gone the next day anyway.

I can't imagine a 'home' antenna that would provide reliable reception from that distance. Prior to the availability of Satellites, there was a 1,000' high "Community" antenna to feed a 'Cable' system with Stations from those area's.
