https://kd9afb.wordpress.com/2014/08/01/a-diy-2-meter-circularly-polarized-antenna/ i plan on building this and reporting results back. similar to the fm broadcast ones i copied years ago in the pic

John, I will agree with everything chuck said with the the exception of the following: But for amateur use where few if any are running horizontal polarity, there is no reason to employ CP. And yes,

Other than the Jampro??? circular? turn style antenna? or Perpetrator? as some call it.? has anyone experimented?? with a? smaller? Circular bay? antenna? that? has? a Horizontal? and

If you're looking at cellular, and using, or thinking about using, Cradlepoint, another option to consider is OpenGear (full disclosure, I work for a company that sells both of these products).

For everybody's benefit, here is an excellent explanation originally to me,from a chief broadcast engineer friend (with his permission)---John

AFAIK there is no longer any place/person or company that can perform temp compensation to crystals as a service. This leaves it to doing it yourself and on most channel elements /? Icom's or other

Hi Neal, Did you get my off net response re a slot antenna? Not the Long Alford Slot as it is narrow bandwidth thus hard to build (for us tinkerers.) Alan VK2ZIW On Mon, 21 Nov 2022 00:10:15 +0000

Adding to what Jeff said. For the example of the JPS-SNV-12 the default switching interval is 250 msec so that switching is at a syllabic rate. It can be set as short as 50 msec but then those switch

Thanks Mike. I had found them as well but agree that the cost is far beyond it's value. I even tried sending the seller a message to discuss an offer. No interest. I'm going to try and source the

Agree, the inductance will slow the pulse but does not remove or clamp it.? A gas tube (old and out dated although effective), MOV or MOV/SAD combination device is necessary to clamp the voltage to a

Chuck, I read your suggestion earlier.? In fact the Motorola Maxar does just that; a resistor sits next to the crystal case. Some sites are off-grid (very low power consumption, like 50 mA on

Thanks for the links. Well SurgeX is shy on diagrams or schematics to more fully explain things though I guess protecting IP trade secrets might be the reason if not for the mentioning of this

Matt, I used a circularly polarized antenna on the WA6TDD repeater back in the 70's and early 80's. The antenna was a single bay antenna made specifically for the repeater by the JAMPRO antenna

MCI had a similar nationwide system with UHF repeaters but I don't know if or how it was tied into the switched network. Anyone from MCI on this list? Our company's warehouse is a former MCI microwave

Good question. Simple answer: no, generally speaking, a regular SNR voter and two separate cross-polarized antennas won't be effective in combatting mobile flutter. The rate of mobile flutter is
