About
Nothing special here. I collect two categories of items. Historical memorabilia and antique telephones.
My focus is primarily on American fraternal organizations, and specifically Knights of Pythias and related orders and sub-orders.

He does a great job of making cables. Dont underestimate Mark's work. Does his homework.

Completely, Utterly Useless.
5 of 15 found this helpful I bought this to use my laptop with an HDMI enabled TV set and also with a projector. Bottom line is its junk.
I spent 5 hours and 2 trips to the store to buy cables thinking my cables were bad. Then contacted the TV manufacturer, then contacted the projector manufacturer.
There was one possible solution offered by the TV manufacturer. That is that this device is NOT, NOT, NOT compatible with High-bandwidth Digital Content Protection. So before you buy this device, check the device you want to hook it up to to make sure that it does not require High-bandwidth Digital Content Protection. If it does, then this will not work with it and you might as well forget it.
Other possible solutions involved attempting to resize the screen resolution, dual and clone display settings, etc. A total waste of time with this product if your receiving device requires this content protection thing.
FYI "High-bandwidth Digital Content Protection" is a preprogrammed hard-wired application built into HDMI devices that requires a code to be shared between the host device and the receiving device. In other words, if the two devices don't "handshake", you lose.
In this case, the manufacturer claims that by connecting the computer to the HDMI port, the current output device (computer) revoked the security key for the receiver (TV set) so that the HDMI is likely PERMANENTLY disabled. Great.
My advice is this: before you connect this device to your HDMI receiver whatever device it may be, check with the manufacturer and make sure it does not require encrypted security keys.
Better still, save your money, time and frustration and find a device that is known to work with your other devices.
Sad day for consumers. Seems this little programming trick with a suicide switch is designed to force you to buy new products even if your old product is perfectly well suited to function as is.

Diamond 770 A Performer.
1 of 1 found this helpful I have two of these. One chrome and this one, black. Both function as 5/8 wave antennas.
Plus: For FM this is a "high power" performer. Its wide band and needs no tuning out of the packaging though you can tune it if you want to, I don't see any reason to do so. The instructions are clear its pretuned at the factory and recommends leaving it there.
Its got extremely good gain on receive, and on transmit it gets your signal out there. SWR's are very close to 1:1:1 - 1:5:1 on most frequencies, only noticed an anomaly at the high end of Amateur 70cm band where it exceeded 1.5:1 a tad.
Works well with a mag mount with no discernible difference in SWR's. Am switching between magmount and lip mount.
I'm going to guess that the base of the antenna isn't so much a loading coil as it is a matching network to achieve the kind of results you get. I'd hate to throw money away to tear one apart to see what's inside, so I'll stick with guesswork.
Drawbacks: Its about almost 4 feet tall so it rides on the trunk rather than on the roof. That affects the transmission pattern. Using an Signal Strength meter around the periphery of the vehicle at VHF the pattern is more signal going out from the trunk rearward than forward. So if you want to point signal North you have your hood pointed South, At 70cm it doesn't seem to make much of a difference due to the nature of UHF.
Some hams buy the PL-259 style mount to use it with a separate ground plane kit as a base antenna.
