    The myth of coax length.

    Yup, copy all that. Since my background is automotive, esp driveability, electrical, and electronic controls im drawing on that base and using that to try and "keep up". No doubt theres a lot i need to learn about rf , ac trans, and so on.....but trying to geta step above your normal...

    The myth of coax length.

    Its related to the wavelength of the frequency. When you read articles about making it the size of the antenna that is usually when talking about a compromise installation where you don't have sufficient room to run longer radials. www.k0bg.com has a wealth of information on. Its an amateur...

    The myth of coax length.

    MOGVZ-Could you go farther on mobile base loaded antennas? Its my understanding that thebase load is to make up for lack of length and thereby match for frequency. Seems the size, style, mounting of antennas on different vehicles will affect output. Am i correct in assuming that mag mounts are...

    Hey guys, have been watching and reading a lot of threads on here.....question on antenna setup. Referring to the thread on antenna analyzers, and x=0, swr......im wondering if itsgonna be necessary for me to invest in an analyzer. Im going to be installing a sirio 5000 as ive talked to some of...

    Hey thanks 222bdfl, yeah, it was a used one, i emailed the seller and she said it was a telex and talked good. Funny tho, the plastic was stamped telex, but when i took the cover off the wire colors were right but not the same terminals as mine on the switch, looked like someone was in there by...

    Yup, I'm hearing every word and believe you're both absolutely right! But I'm a GM tech of 21 years, and diagnostics are in my blood. Here's what I found. Put an extension on the k40 whip and swr dropped to 2- 2.5; put a longer extension on and swr went back up,,,,,,,,,,,lopped off in increments...

    I said at the start my k40was done, swr over 3, and from reading posts the cap is suspect. Haven,t run heat thru this antenna that i recall, took it apart and inspected/cleaned. My trusty fluke sez 0 res on center line and 0 res on shield, hi res shield to body. A couple of questions.....the...

    Wow, thanks guys. I checked the breedlove site, way good stuff. Are you using the 239 connector or the ring mount? Im going on the assumption that the 18' "rule" for coax isnt an issue, have seen lots of pros and cons. Again, trying to go for quality here without breaking the budget, when i get...

    Are you liking the turbo over the performer?? I like the quarter turn and lay down. I get what youre saying about drilling a hole, but that means im going to have to run some sort of stiffening plate on the bottom, the roof on my metro is really thin .....don,t believe it will take the stress...

    Im really thinking sirio right now, esp since it looks like im going to get my early 148gtl back on line and done up. Suggestions for best place/price on the sirio mag mount??

    Mdm-do you park outside or in a garage? Im ina garage, so unhook or laydown is an issue. When i saw a picture of thr sirio it looked like it had a handle on thr base to tighten,loosen. Is that right?

    Yeah rabbiporkchop, i was thinking about some type of quick disconnect, like the ones i used to see on the firesticks. Dtill mulling it over, found my old 102 whip setup downstairs......thought i had gotten rid of it....thank god i was smart enuff not to. I drive a geo metro on my commute, real...

    early (80s) cobra 148gtl

    Well gentlemen, alzheimers starts early. I thought I had gotten rid of my 148gtl, but I guess I was smarter than I thought. In any event- I have, as the title, a 148gtl that I used when I was OTR in the 80s. started in 81. Can't remember if I bought the radio just before or after I started- but...

    Yeah, I realize that the antenna is the key, my k40 was an easy 30 year vet, so i guess i got my $ out of it. The thing is im going to be taking it on and off 2x a day at least 6 days a week, that was what was nice about the k40. While. reading posts here have heard concerns about water...

    Thanks DB- my bad, forgot to mention I was using a mag mount on the roof of a geo metro, never thought about the trucker mount you mentioned. The nice thing about the k40 was i didnt have to unass my seat to pull the antenna. Is the $ for the sirio really worth what little power i'd be running...

    My old k40 finally bit the big one- so I'm thinking Wilson 1000, 5000, or sirio 5000. One thing I liked about the k40 was the 1/4 turn feature- made it real easy to reach up and undo when pulling in the garage. My guess is that the others won't be quite as easy. I do a 1:15 min commute twice a...
