I used to have a 30’ tower, a big antenna and a rotor device mounted on the tower.
@ShadowsPapa in your case depending on distance to the transmitters you MIGHT need to gang two antennas.
All antennas of interest are the same general location, Aleman, north of Des Moines. ABC, CBS, NBC, PBS, all from antennas in that area within a small circle. There’s nothing broadcast from our south or west really except low power, low interest stuff ;-)
This is us - ABC or channel 5 is off to the west a bit more and likely why it’s so hard to pull in with the antenna aimed for the others, but 5 has been an issue for decades, even when it was owned by ISU it was a lower powered station.
@ShadowsPapa…hmmmm a single 4-bay externally mounted antenna should get all of that at full strength. You said yours is mast mounted about 30’ up? If so you should be totally golden.
Which antenna are you using?
It’s a 10 year old (GUESSING!) Radioshack if I recall correctly, it was their top of the line in its day and came out just as the conversion to digital was taking place so it was labeled for digital as well as old analog.
It’s got a couple or 3 of the elements snapped off in the wind - if that’s what you call the aluminum tubes that branch out from the main bars. I’m not an antenna expert, I can rig cable and terminate and such - it’s what I’ve done in a way since I was an electrician/network/phone person for Principal Financial Group and a network person for the state of Iowa for the last 10+ years. TV antenna, no expert, cable, networks, etc. yeah, I’ve got that.
I wonder if the age and wind damage are sort of causing. I was WRONG on the miles. I thought 45 but hey, we’re way under that. I guess I used the miles on the odometer, not as the crow or vulture flies.
Now keep in mind, the height is ground to antenna and the house is a 1 story ranch with a walk-out basement (fully 100% finished into nice living area) and the ground slops so much that the top of my shop is WAAAAY up there, but not if you look from the house to my shop!
We are sort of “down” in a valley area. Iowa is far from flat. We live not far from the Des Moines river and many RAGBRAI riders come to this area to practice and get into shape for their annual ride - that’s how hilly it is here.
Semis have trouble keeping up the speed limit on I80 east,
the 1976 bicentennial train across America had to be pulled by extra engines through parts of Iowa. Mountains, no, abrupt, steep and many hills, yes.
So if 2 or 3 snapped off elements matter, if age matters, hills matter, with multiple splitters and many feet of cable, I wonder - amp or antenna? Or both?
Does your antenna look like this:
Check out this analysis link
the 3679 almost nails it exactly. That’s what it is like and might even be made by that company for Radio Shack (when they were in their hey-day) It sure looked like it.
This is our exact address plugged in - the results -
That first antenna is now being used for deep fringe signals only as (if memory serves) they are VERY directional. No off axis reception. The newer styles like the second won’t do anything far distance but have excellent local reception even off axis. I had mine turned 90 degrees to the local tower and still had strong signal.
May be worth seeing if you can get one from. BestBuy or equivalent to test and return if your signal is no better.
