How To Paint a Mobile Antenna
I had three antennas on my vehicle that were chrome and bare steel. I wanted them to match the color of my black car, so I decided to paint them. This is how I accomplished this project.

How To Find Your FCC Ham License Online
Hello sir! I’m in Mobile, AL and need some help. I’ll buy lunch and a taco for your help. I have a D75. Call sign N0AJX. I can certainly come to you.
This video boils down to this: For base station HF use RG-213/U For base station VHF/UHF (2m/440) use LMR-400 For mobile use RG-58 That's it.

Yes DX engineering is my choice of buying always had good success with them 🤗
How do you change the mic audio control? many complain that my audio is too low on the analog repeaters. THe digital is fine.
Great 'down to earth review' - I was on the fence (overwhelmed by features) but decided to buy one after watching your largely non-technical but common-sense review - thank you (ve3ega)
Very understandable video, thank you!
. Thank you for the info!
I do have a limited space and that's the reason why I bought one the problem is that this antenna is complete deaf, the SWR is good on all bands, except 80 meters, but if I can't listening nobody I can't transmit. So I decide to remove it from my roof.
Great T-shirt!!! Yes, I know what it means.
Why you need to program the yeasu 850-L?
I want your codeplug. My mother lives in Gulf Breeze.
Very nice... May I ask just so I didnt miss anything... Your Indoor Shack Grounds and Outdoor Arrestor Grounds are all on the same Grounding Rod? I am new to this hobby and I want to be certain... Thank You Very much for taking the time to share this... KC3ZDW
Thanks for showing all of the details of how everything is connected. This has been a big help.
You're welcome!
Another single element antenna with a *_”magic black box”_* at the bottom that matches all bands. What sort of electronic wizardry might be in that box? (Other than a resin-potted dummy load?) I would think that by now someone would have reverse-engineered this and similar antennas and come up with a DIY clone … Is it a _”random wire monopole”?_ *73 de AF6AS*
Thinking about picking up this radio but I have a quick question. Can you use a stylist on the touch screen? I have really fat fingers and I'm afraid the small touch screen maybe too difficult to operate for things like using the keyboard to nave your frequencies.
Sometimes you want to keep the color scheme of your vehicle; with me, this was my goal. I took three Motorola antennas with chrome lock-nuts and painted them black to match my vehicle's color. It is not a difficult procedure, but make sure you use paint that is metal-free.
Stephen, wondering how you determined your paints were "metal-free." That super long list of ingredients on all the cans in the store is intimidating. Maybe I need to take a large magnifying glass in the store and spend some laborious time "in research," hi. My task is to tame the shiny aluminum on a couple of antennas to make them more stealth...to next door neighbors, and the HOA!
Greetings. I purchased a new to me comet. The package did not include the paracord kit I do not see anything of it mentioned on the instruction kit. Can you tell me what the unit is called and what size is required. I will have to purchase I have a 30m telescopic with appropriate guy wiring
THE SOUND FAILED ON YOUR DEMONSTRATION!
I think there are some (me) that just want to see how it is done so they can do the same. This all looks very sensible and easy to follow. Thanks for the post.
I get 1.3-1.5:1 across all bands, running RG8 coax. 250 watts? You don’t need it. I have made contacts all over the US & Canada, as well as Europe on 100 watts or less. 35 ft above ground? I’m a little less than 3 feet AGL.
Good one
Nice, clear explanations of the features. Just got mine and am impressed with the radio.
Does anyone make an aviation radio with a 2 m combo?
Love RT Systems software! Their support is also first class. Like your spreadsheet method. Will do that on my upload.
What am I speaking about? I couldn't hear any sound from this video. Listened to other videos you uploaded but there was no sound on this one.
So with my yaesu ft710 where should I place my digital meter
That's a lot of money for a basically cheap 10 meter 5/8 antenna.
Switzerland is wet ! Lots of rain this spring with flooding in areas. Last year was quite the opposite. Yes, although I do love the Kenwood brand, I am leaning towards getting the Icom and just needed an excuse to make that final decision. Excuse provided !😂 It would have been nice to have the APRS but as you say, there is no perfect radio. I travelled to the US a lot professionally as well as for pleasure, always loved being there. You have pretty much everything ! Thanks again and keep making those great videos.
Hi Steve, greetings from Switzerland. Enjoying your videos on the Icom ID 52 and the Kenwood D75. Just got my licence a week ago and looking to get set up. Would love to have your feelings about these two radios (id52 and D75) like if you had to choose between one or the other ?? Cheers and 73’s, John HB9 IMG
Firstly, how is everything in Switzerland? I have visited this beautiful country when I was a child, (back in the 1960s) and actually got to have skied in the Alps! (Thanks for stirring up such good memories!) Secondly, the selection between the two radios is a personal decision; I have both. They are both about the same price and equal in quality, (in my opinion.) The only difference that stand out with me has to do with the battery power. I have had the ICOM turned on for over 24 hours, (monitoring) with significant battery power loss. However, the Kenwood D-75 still has an issue with the battery draining at a faster level. Also, the Kenwood will automatically power down after a set time and there is no way that I know of to override this setting. This is a "battery saving" function that, if you aren't paying attention, (the radio will start beeping,) will shut the radio off without you knowing it. Both are fine radios, but if battery life between charges is important, I would lean toward the ICOM. -Regards! Steve
Thanks PA3CRL
Why erase it?
Personal choice.
No sound ???
What are you speaking about?
They say not to have any wires run parallel past the surge arrestors. They worry that the non-arrested wires flashover to the "protected" lines. They make surge arrestor boxes you can run remote/control type wires through (terminal style, for single conductord or non-coaxial lines). I have one that's 4 wires in, 4 wires out, but they likely make larger ones.
Good point. I see an update on my part coming up. Thanks!
Thanks Steve - much appreciated! 73
Why are hams so f’ing awkward 😂? “Hey, Steve here…” 😂
Good video.
Glad you enjoyed it
You can combine multiple antennas onto one mast to conserve space, but do it cautiously. I also re-explore my ham shack grounding at my entry panel.
Can you show me how to set up the vox
I'll put this on my suggestions list for videos. Thanks.
So the version 1 is what I'm after I assume
Grounding for lightning strikes is useless. If you get a close hit, the voltage/current will roar up the ground to your gear. I was the project engineer for the installation of outside plant and switch at Mt Cook, bought into service Dec 1969. The latest type of lightening protection was used. A severe electrical storm in April 1970 completely destroyed all plant, completely destroying the specially earthed switch. $250,000 gear gone!!!
What does it do on turbo on vhf? I'm worried about the vhf/uhf side being weak?
Turbo is the transmit power, turbo being the highest.
@@K4SRF yeah I've heard conflicting stories of some,units producing 60-70 watts vhf and some barely put out 30. What's your vhf performance like
So love my 878 I’m considering selling my Yaesu ftm500 I use as a base to get a 578uv3 with the BT01 controller what ya think?
It is a matter of personal choice and which radio you are most comfortable with.
Outstanding
Please watch this grounding presentation from the ARRL and you will see everything that is wrong with your station ground. ruclips.net/video/VvE570NPmmI/видео.html I must confess that my station was like yours until the Dayton grounding presentation. A rude awakening for me. I find most hams are doing it wrong. Also you should use bushings where the coax enters the external surge protection box. The 8 GA wire should not be connected under the mounting bolt, it should be on a separate bolt through the copper bar. It should not go through the same knock out hole as the coax on the left., it should have it's own hole.The copper bar in the shack is a "bonding bar", not a ground bar and should not be connected to the ground rod outside the shack. 73 N2SQ
Watched it and plan on making some changes. I'll put out an "updated" grounding video later. Thanks for the input George! -Steve / '73 K4SRF
Much thanks. Helpful as my schooling.
Great to hear!
thanks, great job Steve 73 from kb2uew
You are welcome!
Just got the 850l. No dual comm???!?!? My d74a does so much more than this 850. I think yaesu could have done a better job. -Kd2qql
But does your D74 do the airbands, both receive and transmit?
Could you tell me how to turn on the the recive
Not sure what you are referring to.
TOO MUCH TALK, NO INFO
