I've been looking for a way to switch multiple receiving antennas to multiple receivers. I know some hams are using video switchers but info on them is scarce. There is a Dynair SVA-100B for sale on

Roger, as long as the switch is passive and not active it will work well for you as unused ports are terminate in 75 ohms. I use a 12X1 Dynairs here and they have excellent isolation plus it terminat
Roger, I took a look at this unit and it appears to be an active unit rather than a passive switcher that you need for Topband. You can call Dynair at 858-450-0504 and see if they can tell you where
As an alternative, in my opinion the receiving antenna switching capabilities of the K9AY 8x2 switch are far superior to any available alternative: - eight antenna input ports - two independently con
I'm not sure that I would like pushbutton antenna switching. Especially in a contest. I use a 4-position rotary switch to select all four directions of the two Beverages. (The same principle would ap
I've used the K9AY pushbutton RX select switches at W3LPL and they are a very fine ergonomic solution. Definitely prefer the pushbuttons to rotary switches. At home I use footswitches for 1-of-4 RX d
Do you? I didn't know Gary sold them. Where can we see them? BTW, besides having to rotate this switch only 22.5 degrees,it turns very smoothly. I fiddled with the spring tension and lubed it for jus

It appears that the better video switches need a signal from the vertical blanking interval to switch. No signal, no switching. Probably explains why they are so cheap on eBay! I have 3 bi-directiona
Same here. I have a set of 6 pushbuttons in a circle with indicator lights to indicate which one is in use. They control beverages at 60 degree azimuth intervals. It is much more intuitive where I am
BTW, besides having to rotate this switch only 22.5 degrees,it turns very smoothly. I fiddled with the spring tension and lubed it for just the right amount of torque without being sloppy. In the 197
The early Dynair switches are passive and they only require pushing in the old fashion PB snap switches. The only voltage they use (optional) is for switch illumination which was required to show wit

Tim - The HI-Z system supports feeding two rigs with independent direction selection in so2r. I think this is the right gadget for that system: http://www.hizantennas.com/asc.htm 73/jeff/ac0c www.ac0
Roger, I am using this remote 12 channels switch http://m.ebay.com/itm/281575028616?nav=SEARCH I equiped it with rf BNC connectors into the box and wired into required configuration. I am using it fo
I have several Array Solution StackMatches that came with rotatory switches. I found the rotatory switches to be very awkward for changing stack configurations and I quickly replaced them with MicroH
Since my RAS-8x2 has been mentioned prominently in this thread, I'll give everyone an update... Yes, I still make them! I don't keep any in stock, but usually have some preassembled boards and other
