[Repeater-Builder] Voters

A while back, there was some discussion on voters. I have read through all of that. I am looking to install one here. I am planning on bringing my rx sites back on RF and having the rx radios at the voter site interface to a status tone (2175 Hz) circuit and then feed the voter. My question is

[Repeater-Builder] DB-420B Element spacing

Hi, I have a quired a used DB-420B antenna. My plans are to use it for my 443.65 repeater. After a close inspection I have found that the previous owner must have tried some "tuning". All of the spacings in the vertical plane between elements are different dimensions. So, I have a few question

[Repeater-Builder] Re: What is it?

We are the only tenant on the tower. There is no other radio equipment on the site...and the only tower on the mountain. So it's just us (and we get the site rent free...yay!!) Apparently, someone had three of these sites built in the late seventies. Eventually, they ended up being controll

Does anyone have the connection points I need to install a B&D Enterprises 1P Controller to this repeater? I can trace out the xmit and receive audio but I would like to know where I can access the COS receiver activity indicator (terminal ??). Thank you. Paul N0PL Yahoo! Groups Links

Re: [Repeater-Builder] What is it?

Before you go and cut down this UHF slotted dipole antenna Off the top..  My questions are Do you Own the Tower? or just another Tenant using it?  make sure that  No one using it.  it may no longer be  used for a translator, However  It may still be used by a local LPTV station.  Persona

Re: [Repeater-Builder] What is it?

This looks like one of the old Bogner 8 bay UHF antennas, I would guess it weighs somewhere in the 750 to 1250 pound range.  I believe that Cablewave picked up the Bogner line and later merged with RFS.  With your picture you may be able to get a spec sheet from them.  You could try Bill M

Re: [Repeater-Builder] Re: 2M duplexer question

John, I don't mind letting everyone in on a good deal. Len Pringle is a Ham, and he's Telewave's Sales Manager. Contact Len at <[EMAIL PROTECTED]> Don't waste your time with the non-Hams! Telewave billed me $1,238.25 plus tax and shipping. That's with the 25% Amateur Radio discount. Although

Re: [Repeater-Builder] What is it?

I suspect that the UHF TV antenna weighs in at 1000 pounds plus. From the picture, it appears that this antenna has a flange midway up the array where the array can be separated into two pieces. Possibly you could remove the UHF array in two pieces and better mount you ham antenna. I do not th

[Repeater-Builder] Re: 2M duplexer question

Eric, thanks for the valuable info. I initially budgeted for the 1556 duplexer and noticed this afternoon that it only goes down to 148 Mhz. So I called Telewave and they didn't have a listing on the 1456 that's why I asked abt the 4 cavity duplexer. the sales guy started giving me some story a

Re: [Repeater-Builder] 2M duplexer question

For amateur radio, TX/RX gives 25% off their list price. I find that their four cavity unit is about 88-93 dB. James johnmichaelwelton wrote: >Need to get several 2M duplexers for a hospital project. The Telewave >TPRD1454 (4 cavity, 5 in) provide 77dB isolation (~$750). I'll be >using 40-50

Re: [Repeater-Builder] 2M duplexer question

John, I used CommShop to come up with the minimum required duplexer isolation for a 2m transmitter putting out 50 watts, and a receiver of 0.35 uV sensitivity 600 kHz away. The answer was 87.2 dB. Bear in mind that computer programs like CommShop that calculate duplexer isolation have to make ma

Re: [Repeater-Builder] What is it?

I would join, then post a question to the Tower-Pro group here on YahooGroups.  They should be able to give you an idea of weight.  Any of the commercial TV-FM antennas that I have seen can get pretty heavy. 73, Joe, K1ike At 10:58 PM 9/12/2004, you wrote: We are getting some strange receiver no
