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.
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...
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...
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 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...
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.
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.
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...
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.
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.
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.
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!
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...
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.
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.
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...
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.
