Re: Antenna recommendations?
A signal map may be useful to see which channels are available, signal strength, direction and in which bands (VHF-lo 2-6; VHF-hi 7-13; UHF-modern 14-36; UHF-legacy 38-51). https://www.rabbitears.info/searchmap.php OTA with no fuss. Sounds like an oxymoron. But as kyl416 said. Start with a pair of r...

Re: Lets Talk LTE Interference
Purchased mine in Oct. 29, 2020. It also has the 5-599 / 600-3000 label. Though the third party frequency response measurements I've seen were done Feb. 12, 2020. -3.3 dB on channel 36. That's about the same as a two way splitter and similar to the third party measurement I've seen of the SD filter....

Re: Lets Talk LTE Interference
Have you actually measured the frequency response. Others have. I have that device. I can see the label for myself. Labels are marketing, not specs. I have copy of the spec sheet as well has actual measurement results done by a third party. You obviously have access to necessary equipment to do act...

Re: Lets Talk LTE Interference
For me the channelmaster did indeed negatively affected things on 35 and 36, SD's filter did not even though being told that it (CM) should be 608. Frequency response comparison should be able to confirm that. But the only frequency response comparisons that seem to be publicly available do not. Su...

Re: Lets Talk LTE Interference
I posted about that in different thread several months ago. CM said the 600MHz on the label referrers to the 600MHz LTE band. Not the the filter spec. That also coincides with actual test results that have been posted in the AVS forums. Where it is down about 3.3 dB at channel 36. That is similar to...

Re: Lets Talk LTE Interference
Probably could be but would require a dynamically applied filter depending on mode/what is tuned in. Probably not worth the cost for it to be built-in. Besides many antennas are split to multiple devices/tv's and thus should have an external filter anyway.

Lets Talk LTE Interference
I have some mixed feelings about posting this because I don't want to promote SD LTE filter sales. But there seems to be some misunderstandings about LTE interference and the use of an LTE filter. Though by well meaning people I think it tends to mislead people into thinking they don't need a filter...

Re: LPF-608M LTE FILTER
According to CW's review on Amazon with measured specs.
"Ch36 (602,608MHz): -2.2, -4.7dB respectively"
From specs I've seen this is substantially the same as the Channel Master LTE filter.

Re: New Silicondust LTE Filter
We've seen spec sheet of the Channel Master LTE filter and 3rd parting test results. Where is the SD LTE filter spec sheet and test results?
An extra 99 cents for the SD logo. Oh and it looks like plus shipping too.

Re: Channel Detection Scan (channels 2-6)
Antenna physics didn't begin with HDTV. The modest bowtie TV antenna many people and I use conforms to physics. That's why they were designed and built. That's why they work. The modest bowtie that has about 30" of 300 ohm twin lead was common place back in the days of analog TV transmission and wer...

Re: Channel Detection Scan (channels 2-6)
Go back and look at the conditions I cited. Within 20 miles LOS. That frequently results in favorable reception situation. Very modest antennas can and do work very well in those situations. Even for VHF low band. Piece of wire, single rabbit ear, 13" x 3" bowtie. A dedicated antenna for VHF low ban...

Re: Channel Detection Scan (channels 2-6)
Don't believe every online calculator you see. That calculator also thinks a ch. 10 (195 MHz) bowtie would have to be about 4 feet wide (2 feet each side). When I know for a fact that a 13 inch wide (6 inches each bow, 3 inches high, and 1 inch feed point gap) works just fine. Gets 100% indoors at 1...

Re: Channel Detection Scan (channels 2-6)
Yup. A folded dipole is what I was going to suggest giving a try. Though twin lead doesn't have to be used. Even if not using twin lead a 1:4 balun should still be used if connecting to coax. i.e. 75 to 300 ohm "transformer". It does more than just match impedance. It properly converts the balanced ...
