What the maker puts in writing
The list runs to ten bullets. Five of them are unique:
- “Parental Control to Manage TV Programs and advanced Closed Captioning”
- “Simple Connection to TV with supplied RF Cable”
- “Analog Pass-Through for Low-Power TV Stations broadcasts”
- “Digital TV Tuner Coverter Box”
- “On-Screen Program Information with Remote Control”
Then the same five again, in a different order, with the same spelling of “Coverter”.
Plus the description: This New converter box is great and includes Analog Pass Through, Universal Remote, and comes with AV cables.
The pass-through was the point, and its moment has passed
Analog Pass-Through for Low-Power TV Stations broadcasts.
Worth understanding, because the feature is genuinely clever and genuinely dated.
A converter box normally takes the antenna signal, decodes the digital channels and outputs them. Anything analog on that same cable is blocked — the box simply does not pass it.
Pass-through lets an analog signal continue to the television untouched, so the set tunes it directly.
Why it mattered: when full-power United States stations switched to digital in 2009, low-power stations and translators — small transmitters serving rural areas and city neighborhoods — were given a longer timetable. Many kept broadcasting analog for years afterwards, and a box without pass-through made them disappear.
That deadline has since passed too. So what the feature now helps with is other analog sources sharing the coaxial: a VCR’s RF output, a camera modulator, an in-house analog channel.
No other box on this shelf has it. On most installations in 2026, that is not a reason to buy.
The cables and the remote are the real argument
Simple Connection to TV with supplied RF Cable… includes… Universal Remote, and comes with AV cables.
Three things in the box, stated — which on this shelf is rare. Only ZJBOX matches it, with an HDMI cable, a composite cable and a 1 year warranty. Mediasonic supplies a 5 ft HDMI cable and a large remote. The other seven itemize nothing at all.
And the universal remote solves a problem the category creates. A converter box adds a handset to the room: you need the television’s for volume and input, and the box’s for channels. A universal remote carries a library of manufacturer codes — enter yours, and one handset runs both.
The alternative on this shelf is iView’s learning remote, on the 3500STB III and 3500STBA III, which copies infrared patterns directly from your existing remote. A learning remote works with anything, including obscure sets; a universal remote needs your television to be in its code list, which for a very old set is not guaranteed.
But what it does not have is most of the category
No recording. Eight of the ten boxes here record. No USB. No HDMI — the connection described is the RF cable. No Clear QAM, which six boxes have. No ATSC version stated at all. No storage limit, no front display, no timers, no EPG.
For comparison at lower prices:
iView 3300STB — $28.95 — ClearQAM, recording, 4 TB, a built-in clock
iView 3500STB III — $32.96 — ClearQAM, recording, channel 3/4, HDMI, A/V, learning remote
allaboutadapters DTV105 — $38.30 — four simultaneous outputs, S/PDIF audio, time shift, an EPG, a large LED display, last-channel memory, metal case
Mediasonic HW250STB — $39.99 — the ATSC 3.0 warning, firmware V1.7, a sub-channel front display, Dolby Digital, a channel 3/4 hard switch, 5 ft HDMI cable
So $66.91 buys the pass-through, the cables and the universal remote — and leaves out recording, HDMI and USB, which all four of those cheaper boxes include.
And the ATSC question is unaddressed
The bullets say “Digital TV Tuner” without naming a standard.
ATSC 1.0 has been the United States digital broadcast standard since 1998. ATSC 3.0 (“NextGen TV”) is the successor — 4K, HDR, better reception — and broadcasters are transitioning station by station, so a 1.0-only box stops receiving a channel once it moves.
Only the ADTH at $159.99 handles both. Only Mediasonic at $39.99 warns that it does not: “This Box does NOT support ATSC 3.0.”
Given the analog pass-through, this is unmistakably a 1.0 design — the feature exists for a transition that happened before 3.0 was written.
Also unstated
No antenna, which every box on this shelf needs and only the Tablo supplies. ZJBOX is the one that says it plainly: “requires an external antenna… It does not have signal reception or amplification functions.”
No warranty term, where ZJBOX publishes one year.
748 g and 163 × 216 × 46 mm are published — the heaviest box here, which on a device with no recording and no HDMI suggests an older, more generously built chassis.
