I don't think color matters much for UV protection. I had a 20 year old fiberglass antenna painted OSH white in perfect condition.

Customer support that actually answers the customer's question!? Amazing! My speculation is that black will do the best job of absorbing light and protecting the fiberglass.? I would suggest a final

OSH spray paint is made by Rustoleum. (I'm holding back on the real deep paint nerd exposition.)

KIO recommended Rust-Oleum in a flat black to paint the spreaders. The Rust-Oleum website had a gazillion paints to choose from so I sent a message for their recommendation for painting fiberglass and

No, Cliff is not crazy when he says go to OSH. The old "OSH" which was Orchard Supply Hardware did go out of business ?years ago, but there is a new chain called "OSH" for Outdoor Supply Hardware. We

I recall some comercial antenna painted a light grey blue.

I'm not saying it's not possible to blow the finals. I'm just looking for the side-by-side test or measurements compared to specs on the same radio with and without zener, and am surprised that I am

Hiroki did it twice.

Connie,? when you blow your finals. (Not if, but when), I have plenty of replacement transistors,? which are not trivial to remove.? Lol. Doug

Is there a side-by-side test documented anywhere? Ie, showing that the radio is destroyed without the zener diode under the same conditions otherwise? I couldn't find one. They're cheap -- you'd think

I installed a Zenar diode to protect my (tr)uSDX against high SWR and replicated the same experiment conducted by Barb WB2CBA (the video I forwarded to this forum a while ago). With a dummy load the

Consider grey paint, less visible

Joy, about painting; Any kind of enamel will work to protect the fiberglass rods from UV. Go to OSH and get a big can of their brand spray black enamel. Gloss or flat, your choice; heck you can use

Paul, The way my "MacLogger DX" logging program works is, it gives you a spreadsheet like list of spots from its spot cluster. When I select a spot from this list, it tunes the radio to the selected

I use the makers rotor controllers.? One less cable, plus computer to configure. Besides, the computer logger can't guess what station you are trying to work until you are ready to log the QSO.? On

Do you just use the controller that comes with the rotor to exclusivity rotate your antenna, or do you add a third party box that allows you to have the computer control your rotor with your logging

I plan to be there for lunch but I will have to leave afterwards. Joy
