    Anyone know of a good antenna for murs? I see fire stik is making a Murs base antenna. Seems to be good but I wanted some opinions. Thanks!

    Cheech,I used a J-pole made from 1/2" copper for mine and it worked great for me.Then I went to a Ringo Ranger 2-Mtr and
    it works better yet.The J-pole was cheaper of course!
    You can use several ant calculators for J-poles.Just do a
    Google search and they will come up. I did make mine adjustable. Good luck sir.Slim

    What kind of antenna do you want?

    I have 2 4-element quads designed for MURS by Cubex. It is the same antenna as the Yellow Jacket, but re-modled for MURS. It's very light and an awesome antenna. He has more in stock and at approximately $55.00 each, its hard to beat!

    If you want a rock-solid vertical, order the Hustler G7-150-1.
    (I don't support DJ Electronics per say, its just a good link with specs)

    Other than that, I've made a number of copper J-poles and they work pretty good. If you do decide to go with a J-pole, design it for 153.210 MHz.

    vhf maul

    I guess i'm a bit late onthis conversation, The best thing I've found is an old super station master, a 10db gain vertical. there all over if you look. I payed for one and collected up 4 more shortly there after. At 24 ft by 3" in diameter not too many people want to put these things up. with ten watts i was talking over 60 miles with no problem, with 200 watts over125 with no problem. these are buy far the best murs antenna. they are a high gain colinear antenna so there band width is a bit tight. you can tune them for best center freq, for perforamance and durability these repeater antennas are smoken!

    hey there..

    i think more people should use MURS..
    it is often over looked and yet being so close to 2 meters with nearly identical operating as 2 meters..

    Myself i use a Comet GP-9
    this is a high gain colinear antenna of 10 dbi for 2 meters

    although this is a dual band antenna for 2 meters and 70cm band (is slightly higher db gain for 70 cm band..about 13.6 dbi)
    i can tell you it works great on murs..

    with 50 watts i have spoken 130 miles
    but then the antenna is on 20 ft of mast while on top of my 3 story building (with guy wires..lol) so it is 52 or 54 ft high at its base..and the antenna itself is 18 ft tall..

    if i ever replace this antenna it will be it will be with another dual banded antenna of a high gain colinear antenna being 24 ft tall with a gain by Dimond like this http://www.rfparts.com/diamond/x700hna.html

    well good luck

    Later

    you might simply want a mono band antenna that is specificly tunable for the frequency you want...so try this maybe

    station master

    cheech, I dont have any photos but you can search for cellwave antennas look up 150 meg superstation master. this thing worked so well I had to mount it 10ft off the ground because at 50 ft I was disturding out lying emergency services that were still on vhf, the next best was the hustler vertical, the lower gain ametuer dual band antennas like the x50 had an exceptable swr in the murs operating range but as you go up to the higher gain dual band antennas the band width tightens up and the swr is no longer acceptable, If your looking for off the shelf tunable for the 150's region the hustler is high gain and very durable. It takes a little work to get each of the 3 5\8 sections tuned for the lowest swr. If you dont take the time to tune it down to the lowest swr you will encounter alot of phase distortion.. if you can't find a station master a hustler is a good second choice... good luck Steve44

    Hustler makes a series of antennas for amateur, CB and LMR (land mobile radio) use. I think that an LMR antenna is a good way to go, and you might check out the Hustler G series antennas for the MURS freqs.
    Hustler G7-1

    These guys sell them on eBay
    DJ electronics G7-1


    Be aware that these antennas use N type connectors, which is best for VHF/UHF frequencies, in terms of (less) loss.

    Cheech, another antenna that we have had good results with is the ARX2B ringo ranger II {mentioned in an earlyer post by another member}. We have been running on vhf for about 10 years on dot and star freqs before murs ever was . the ringo has been used as a standard in the high desert with great results in the 150's region I think they go for about 59bucks, the last one I bought was, This antenna is tunable from 136 -164 megs 5.5 db gain team it up with some 9913 or lmr 400 coax and you've got inexpencive high performance,, All the antenna's I have mentioned I have personally used tuned assembled and tested having experenced people such as jay , the late Great Bill Good, Phil oo6 and myself using calabrated recievers and attenuators to monitor signal strengths The ringo is the most bang for the buck ... Once again good luck, and keep those out dated buisness banders off our murs!!! Steve 44 A-1 antennas

    Ok got an idea for antennas but what about radios. What are you guys running as far as radios? 44 I see you mentioned old business band radios not working good or something? What about the new ones? Or is it the power level some put out? Thanks

    Yeasu 2500 \ kenwood tk705

    the yeasu 2500 is a ametuer radio but the reciever is pretty broadband,, these radio are built to mil spec standards and are almost bullet proof. they are not manufactured any more so you have to find them second hand, stay away from the 2600 its crap the kenwood tk 705 is a commercial radio thats user programable and is also very durable,, the yeasu does about 50 watts and the kenwood 25, these are my two favorite loudest most durable vhf radios, the Icom v8000 is ok it does about 70 watts but is not quite as durable, the ametuer radios need to be modified to transmit in the murs region, yeasu clip the green wire icom remove a chip capisitor very easy ,more info on mods go to mods DK, and theres lot of commercial grade amplifiers avialable, If yor gonna run one stick to the commercial ones there much more durable than the ham guy ones ,, that pretty well somes it up for murs, good luck!!!
