Antenna amplifier works with small Yagi but not with large replacement Yagi?

small antenna w/amp that came w/antenna gets ~105 channels, w/o amp gets~26 channels

large antenna w/amp for small antenna gets ~26 channels, w/o amp gets ~105 channels.

solution is obvious (don't use mis-matched amp), but what is the theory behind this?

I noticed the same thing w/bow-tie antenna - generic amplifiers either make no difference or decrease number of channels received.

malwarebytes fails to scan Mac email folder by default?

I used the trial version, expecting it pick up all the trojans they send as pdf attachments in fake invoice scams like geek squad (e.g. Phishing.PSQUAD), but in 2 weeks it didn't detect any of them. I assume if I get the pay version, it still won't scan email automatically. Since I already know those emails contain trojan pdfs, all I need to do is ignore them, don't click on anything, and let them go to spam folder. malwarebytes AI chat said to use drop-down (contextual) menu to scan a folder (not a file), but the term malwarebytes doesn't appear in any contextual menu in trial version. Chatbot also said to use "advanced scan", but that also isn't found in trial version.

I'm guessing this should go in one of Mac subs, but they don't allow reposts or posts w/o flair, whatever that is. The bottom line: XProtect is supposed to block these trojans anyway, so there's no point in wasting time with non-functional software.

Is it safe to use 1425 Watt inverter to 12-volt battery of Nissan Leaf?

Is it safe to use 1425 Watt inverter with 12-volt battery of Nissan Leaf?

Does it pull 100 Amps DC? I'm assuming the charging voltage from 40 KW battery is 14.25 VDC.

What is maximum DC amps the 40 KW battery can supply safely for running a fridge?

Attaching 1425 Watt inverter to 12-volt battery of electric car: does it pull 100 Amps DC?

Attaching 1425 Watt inverter to 12-volt battery of electric car: does it pull 100 Amps DC?

If the charging voltage from HV battery to 12V battery is ~14.25 V, does this mean it's pulling 100 amps at the charging point?

Can #6 cables with 5/16-inch ring terminals handle that continuous load?

I'm really doubtful that this is safe or sane.

Re: attaching car battery to inverter with 5/16 inch cable ring connectors?

Re: attaching car battery to inverter with cable ring connectors?

The instructions say to attach termnals to posts, however every car battery

so far has posts much larger than 5/16 inch.

I'm guessing the vendors don't distinguish between posts and the threaded

5/16 inch or 1/4 inch screw clamps holding the car's cables in place.

Docusign phishing email from liefloop.de

I received a Docusign phishing email from domain liefloop.de. The sender was buried several lines down in the full headers, but hidden from view to casual users.

It contained a 12-digit confirmation # and title "Secure Doc". It looks like I can't post it here as it contains personal info (my email et al.)
