Re: Combining two signals at the opposite ends of the FM band

Expensive--but if you were able to build a 400' tower (assuming typical Iowa terrain) and use 4 bay antennas, then you could stagger the antennas, keeping the TPO to around 10 kw for both stations. Sounds like this is the simpler approach, keeping separate antenna systems, one station on top, then ...

Re: Combining two signals at the opposite ends of the FM band

Both stations only need about 100 m HAAT (88 m AGL) and 25 kW each. If tower space was tight in the area it might make sense to combine to maybe save on high lease terms. Beefy tower with separate antenna systems seems like the best bet. Or maybe two lighter towers 15 or 20 ft apart?

Combining two signals at the opposite ends of the FM band

Friend's station in IA was approached by a non-comm station for tower space. Problem: tower too light to support any more bays and coax runs, combining the two stations into one antenna would cost almost as much as a new tower. Eventually they'd like to build a joint tower elsewhere. Given they're o...

Re: Designing website with Muse,Wix,Weebly vs. straight HTML

No, I'm certainly not interested in learning HTML myself. I have used Muse before, which makes a very attractive website but I'd still have to figure out how to integrate CMS into it, which my previous attempt didn't need. Seems like a waste of time. Hiring someone to design a custom site in HTML wi...

Designing website with Muse,Wix,Weebly vs. straight HTML

I may get charged with heading up a revamp for my friend's radio station website. It needs to be fast, not flashy, and simple in design. Which approach would yield a website that will load quickly on smartphones, especially in a slow, rural cellular environment? I could design a site myself with one...

Re: TOH time tones

He was also amused at the story of how WGBB used theirs at different times of day. During the day when they had to hit the TOH dead on it would be right where you would expect: immediately before the news sounder. But at night on hours they didn't do news they didn't bother trying to hit it and jus...

Re: FCC announces first steps in the Repack

Perhaps with the underwhelming outcome for the reverse auction, we can finally put a stake in the heart of low band VHF. And with the end of the freeze, maybe the terrain shadowed valley where I live in Colorado will get a translator for PBS and Fox so I can cut the cord, or rather, break the Dish.

Re: FM bays on a grain elevator stack

Side mounting 150 ft of Rohn 45G tower alongside the stack is looking like the best option. The risk is just too great that spending a few thousand on structural engineering fees would result in finding out that mounting the bays directly to the stack w/a 5 ft standoff would be a no-go. Can't avoid ...

Re: FM bays on a grain elevator stack

Back when I was working on my ill-fated LPFM that was in a forest of translators, all within 50 ft of ground, power density was a big deal. It was around 500 µv/m...at least the hill was on prison ground and definitely not accessible to the public. Assuming: S = (33.4 * ERP) / R2 where: S = power de...

FM bays on a grain elevator stack

If it were a tower, it would be a 10 ft faced monster. Yes, this is an ugly proposal, but the site restriction area has only one real tower owned by one of those totally unreasonable cellular companies.

Re: Ever hear of top-mounting antennas on angle-iron tower?

That's for sure...Even though most of the population would be on the front side of the tower, in theory we might get a nice bump in that direction. But we all know how theory works. All but ruled out top-mount. Best hope now is that we can do a pole mount from stand-off brackets, hoping that with a ...

Re: Ever hear of top-mounting antennas on angle-iron tower?

I just assumed that the OP knows to file for the CP mod, but these days... Ummm, that never crossed my mind. :roll: Without a doubt, top mounting and a 35' pole will mean the landlord will have to file a change for the ASR. Thinking out loud as I type, the biggest stumbling block I think we might h...

Re: ERI burnout

When is the last time each was pulled apart for PM? Ten years is a long time to go without PM. ERI is the best in the business, but even the best will fail without proper maintenance. See how long you can drive a Benz if you never change its oil. On another note, our local tower guy has made an emp...

Ever hear of top-mounting antennas on angle-iron tower?

That's the question I'd like to pose to the esteemed panel. Found a tower used by a utility company for communications. Has several large microwave dishes. It's a big face angle iron tower: 54 inches wide. Option one is side mounting part-way down the tower, but we'd need to find a different transmi...

Re: Roll yer own FM DA?

Here comes the OP, and It's been awhile since I've been over here to the board. $25k for a DA is money better spent towards building a tower near the fully spaced allocation point. And rolling one's own DA, I figured that was good for a laugh. (Especially in light of the recent "Where did my to...
