    VHF Antennas for RF 4 and 7

    I'm wanting to DX the low band. None of my market local uses it. WMC in Memphis is still on RF5 and around 100 miles away. I am thinking about maybe modifying it with a dipole for RF2 and maybe RF6. But I am curious on how efficient it is currently for the entire Low band as-is.

    VHF Antennas for RF 4 and 7

    I bought one last year with this in mind. Thanks.

    VHF Antennas for RF 4 and 7

    Found these in a ditch today! Measurements and dipole calculation shows they are for Ch 4 and 7. Makes sense because the local NBC and ABC were 4 and 7. How good would this RF4 antenna work for the rest of the low VHF band? I need something for my system that can catch low band to go with my...

    Powerline Interference?

    Roku needs a menu for their secret screens in the UI. I get tired of the remote cheat codes

    Powerline Interference?

    I have an update to share. I actually bought a repack ready Datboss Mix, and the active element/preamp assembly snapped right into the older Datboss UHF model. I added the Jan Jenca VHF-HI bandpass filter between my Stellar Labs yagi and preamp too. The results have been great thus far. My...

    Powerline Interference?

    Great thinking! I completely forgot about using a separator. I believe I will stick with JJ on this one if I am satisfied. The flatness and low loss is what sold me. Hopefully it performs as advertised. How weatherproof are the enclosures he uses?

    I see your CM suggestion and I'll raise you this: VHF band-pass filter,174-216MHz / 0,8dB loss, VHF band-pass filter CH7 - CH13. | eBay

    Powerline Interference?

    I did a little analysis on my antennas and UVSJ. My UVSJ is working well, but notice the Televes Datboss UHF needs no extra filtering of VHF band signals 50-250MHz. My UVSJ helps tame a lot of UHF signals picked up by my Stellar Labs yagi. I do need additional broadcast FM filtering for the...

    In the process of installing 30' tv antenna tower

    I might get a new Mix LR and physically disconnect the VHF section if I go nutty enough. LOL.

    In the process of installing 30' tv antenna tower

    That is a bummer. I get that it costs mucho dinero to redesign things, but I really would like one. The preamp being built in was a selling point until you have LTE as low as 615MHz showing up on the analyzer. The filter after the amp helps but I hope the LTE isn't messing with the AGC in the amp.

    In the process of installing 30' tv antenna tower

    The new Ellipse is impressive based on your results. I have the UHF-Only DAT Boss LR too. I think I just need a new snap in active element with optimized RF14-36 preamp assembly.

    Powerline Interference?

    Yeah. I found some strong signals in the 700MHz area. Unfortunately, my Televes DAT Boss UHF antenna seems to be an older design (RF 14-51) and the amp is directly connected to the driven element. My VHF is amped with a Televes T-Force single input preamp made for RF 14-36. I can connect the...

    Amazing what difference this Channel Master LTE Filter makes when you look at the spectrum.

    Powerline Interference?

    My analyzer is coming tomorrow. Hopefully everything checks out fairly clean. I did a cell tower search. My closest one to my south happens to be on the same ridge my OTA signals are bounced off.

    Powerline Interference?

    Thanks for that info. I did a slight tilt. Results are fairly good. I am not comfortable on my ladder enough to tweak the tilt setting 3 or 4 times to find the sweet spot.

    Powerline Interference?

    Signal Meter pictures for RF7, 12, 22, 24, 30, 32, 34, and 36... 24 and 36 come in and out, but no issue. I don't watch them. All in all, everything is great. I'm just a little surprised that my ABC on RF22 is 15% lower than before.

    Powerline Interference?

    I had to install directly on the mast. My pillow block bearing needs a mount bracket welded to try this on my rotor. (Shame you can't easily get a TV rotor support bearing...) But the signals are booming in!

    Powerline Interference?

    I might try a slight upward angle. Both antennas allow it with the mounting hardware included. Thanks.

    Powerline Interference?

    Got it covered. Lucky I found these for $2.49 each back in 2019. The ebay prices are ridiculous.

    Powerline Interference?

    Thanks. I was under the impression that VHF suffered EMI more than UHF. I am also setting up a dual antenna system to cover VHF-Hi with a Stellar Labs 30-2476 yagi and UHF with a Televes DAT Boss LR. My current Channel Master Masterpiece 100 is just not cutting it for my situation. It was more...

    Powerline Interference?

    I have that filter and I will try it. Oddly enough, when my antenna is directly toward RF34, it's my best signal. I think it is likely the diffraction. My network signals have to bounce over a ridge. RF34 is coming over different terrain.

    I'm using a Televes preamp with a 5G filter. I hope it is not dropping the ball

    Looking for a VHF/UHF Combiner

    Pre pandemic, I found an obscure site selling ASKA UVSJs for $2.95 each! I bought 5 for the future. 0.5dB loss rating. I don't know if they pass power. I use mine after the preamp power inserters behind the TV. Dual coax into the house for OTA.

    Powerline Interference?

    Has anyone here noticed interference from nearby powerlines? I had my antenna up around 32ft and my local NBC on RF32 barely locks with around 16dB C/N. My CBS on RF12 is stable at around 25dB. My ABC on RF22 runs around 27-28dB at ~32ft. Antenna looks thru the powerlines around 45ft away...

    Channel Master 40ft Mast CM-1850

    I think it looks pretty good. Hopefully the neighbors can handle it... someone reported my '89 Ford Van to code enforcement as a "non operational vehicle" Code officer came by and asked if it ran. I had driven it the day before... so I started it up and he tore up the ticket.
