Storm Chaser & Ham Radio Operator wants a Lucid Air

Leasing is so complicated

My (very simplified) rules of thumb for these are:

100kHz-10MHz - chopping frequencies for the current modulations and a few of their harmonics (base frequency can be lower than 100kHz or variable frequency, depending on topology and EMI/efficiency constraints)

10MHz-300MHz - FET drivers and the t-rise/t-fall times of the FETs themselves plus some harmonics (quick sampling of the Wolfspeed SiC FET catalog has their t-rise times of 28-67nS, t-fall times of 13-37nS)

These are my personal guidelines when looking at power supplies. Shielding, slew-rate controls and filtering will have a big impact on how much noise leaks out. YMMV.

Tnx. This is useful info. The antenna is due here tomorrow (04 sep). I should have time over the next 2-3 days to mount the antenna (if it fits) and then connect it right into my SpecA. I'll do some sniffing around the car if indicated.

UPDATE - Just received the antenna/mount kit and did a rough, trial installation w/o using the mount's adhesive pad. It fits with an inch to spare below the rubber coaming around the garage door trim. It turns out that when Diamond spec'd the antenna length as 40.2 inches they were including the added height of the mount. But the antenna element is only 38.25 inches long. So um good to go. And the RG316 coax fits perfectly at the corner of the trumk lid without pinching. I'm tied up the next 2-3 days so I won't be able to tackle it as quickly as I'd like. Standby for further.

Pics or it didn’t happen.

 

[fpmacko]

It hasn't happened yet. Pics planned when I install it in the next coupla days. There wasn’t anything to take a photo of because all I did was park the Air logo below my garage door opening and then hold the mount and antenna in place above the logo to verify that it cleared the overhead coaming.

The mounting plate will need a very subtle bending to be sure it conforms to the slight curvature of the C-pillar. It’s definitely gonna work. Even the coax fits snuggly under the trunk lip without being pinched.

I would be interested in this very much as all Ham Operators understand that with a good external Antenna that is tuned to the frequencies you are on, makes all the difference. My questions;

What is the ideal placement, and is the glass Canopy on my AT a showstopper ? Would a trunk Mounted Antenna deliver reasonable TX/RX performance ?

I'm also a ham. I have a 2025 Air PURE. My IC - 208H works well sitting behind the screen, fed with 12V from the trunk. I solved the antenna problem by using a suction cup from an old HP GPS mount. Thin coax is fed through trunk lid seam. All works better than the 6 M Saturn 6 Halo on my 56 Merc. 73
