    I agree that coax feedline is VERY important at VHF/UHF.
    Generally speaking, Times LMR-400 for up to a maximum of 70 or so feet........    At 70 feet or more, Better coax is a must. While Times LMR-600 IS good stuff, It is kind of expensive, AND connectors are Very expensive!  For less money, Usually a person can find some good used Heliax complete with connectors at a swapfest.... (1/2" or even better, 7/8")

    I dont know if that would be the best ever but i had very good results with the famous Comet GP-9. It is a dual-band antenna, mine had been up in the air since 2000 and is still strong going. Look-it up online if you wish, on 2 meter it is a 5/8 wavelength x3. 73's

    K9KJM,

    Good point.

    For my more permanent station setups, I've usually used 1/2" Heliax. The thought of using 7/8" Heliax for a home station makes me drool.

    Wow, did I really just say that? I guess I really am a geek. [​IMG]

    Impossible, based on size. All these "amateur radio" VHF-UHF colinear vertical models have impossible gain figures. The standing joke is they're based on "dBgcl," which is "dB over a garbage can lid."

    That doesn't mean they're bad antennas. It just means the gain claims are ridiculous.

    I've installed and used a lot of the Diamond (brand) VHF-UHF vertical colinears and they're pretty good. They're not Stationmasters, or in that league, but of course they're much lighter and less expensive.

    The only "weakness" I've found with the Diamond antennas (and this applies to Comet - Tram and any of the other lightweight fibreglas antennas) is that they won't hold up very long under very high winds, or being hit by a large bird. No kidding. I had the X500HNA installed on my tower a couple of years ago and one day found it snapped in half, with the upper half dangling, supported by the internal "radiator" wire. Since there aren't any neighborhood vandals who are 65 feet tall, I figured a big bird probably flew into it. That kind of stuff does not happen with a Stationmaster! But then, the 2m Stationmaster weighs about 25 lbs, and the Diamond probably weighs about 2 lbs.

    Not a bad choice, but the "tall" (long) models won't last forever. The shorter, lower-gain models probably last longer because there's less stress on the fibreglas tubing.

    I simply hate "best" hands down threads! [​IMG]

    Almost as much as I dislike little, yellow smiley faces!

    Hello,
    I use the CATV hardline for my 50mhz and up stuff. Works great and the SWR is not a problem ether. I use a homemade connector too. I get my CATV hardline from the guy next door to me. To them a 50 to 150 foot spool end is useless, but to me it's just right. You might try looking into that if you can find a local CATV hardline installer. Around here they will give it to you as they have to pay to get rid of those spool tails.

    I use 5 watts FM for 200 miles?
    how distant do you think you are gonna get 200watts for?

    I use a Diamond X50A, with RG-213 and with 50 watts I can work repeaters 100 miles out. That is with the base of the antenna at a mere 25'.

    Very possible. Remember, the repeater's doing most of the work!

    It's how far you can work on simplex that is more an indication of antenna performance.

    I can work repeaters in Baja California (XE2) that are 150 miles away, with an HT from my living room couch. They're just very well sited repeaters!
