    Can't get SWR on 102 whip below 2.0:1

    I was mistaken on the height I stated earlier. I had the wife help me measure it. Mounted to the bed makes it about 12' 6" off the ground, on a mast putting all the antenna above the roof puts it at 14' 6". Either way, no drive thru's for me as most are 9'. Also when I get the stock lift back...

    Can't get SWR on 102 whip below 2.0:1

    Your last sentence goes for me as well. That's good to know that you didn't strike any lines goin down the road. I did read a few minutes ago from this post that those R. Shack whips are tough as hell, and the experiences some guys had and them hitting stuff. I read somewhere here that a guy...

    Full wave 11m horizontal co-phased antennas

    I haven't heard of "reversible ZL special" what is that Rick? Well I didn't put the feed point on the sketch because I wasn't sure of it, being co-phased in all. But I figured (possibly out of ignorance) that a full wave might me better than say a 1/2 wave, I really don't have anything to back...

    CB co-phased antennas

    I see what your talking about, that totally didn't come to mind when I sketched that up. I have read about that before in a CB book I had years ago. It had good plans for a circular polarity Yagi in it. I just like the big colossal antennas that all the non-Hams will look at driving by...

    CB co-phased antennas

    Another thought After reading this thread http://www.worldwidedx.com/cb-antennas/100792-truth-according-firestik-get-drink-snack-lol.html I kinda feel like a jackass for posting this earlier quote from that link. Which goes to show you that not all information on the Internet is exactly...

    Can't get SWR on 102 whip below 2.0:1

    BTW I can't imagine what things he may have hit with that thing probably being about 15 ft in height. With his truck being a 4x4, his roll bar is about as high as my roof on my Ford (it was lowered for some ungodly reason by the previous owner) If I mount mine on a mast just above the roof...

    Can't get SWR on 102 whip below 2.0:1

    I am getting ready to mount my 102" whip, I assume it is the same Radio Shack one. I am planning on mounting it to the front panel of the bed right behind the back glass. I have a 03" F-150 with solid back glass. But the antenna measures (mounted to the angle bracket, measuring from the top...

    need help on getting/making a 433.9 MHZ antenna

    Maybe a pair of small cantenna's with 1/4 wave antennas in them. If you could fix semi-rigid mount arm on the receiver unit and affix a small cantenna, that would solve your problem. Also give a highly directional work area for the signal. I mean if you have any concerns about a passing by...

    Full wave 11m horizontal co-phased antennas

    Google search and images searches have nothing on it. I wonder if it would work well to shoot skip in two directions. sorry for the weird resolution on the pic, I had to resize it for the forums liking, hope you can read it all. -Bill

    Full wave 10m horizontal co-phased antennas

    Google search and images searches have nothing on it. I wonder if it would work well to shoot skip in two directions. But I would be using a 200 watt amplifier and I do not have a metal roof, would this be inadvisable to transmit this power while under the antennas in the house? I mean I...

    A strange antenna question

    I have buddies that have them, but it would be nice if I knew where that antenna was. It had a nice cast in so-239 connector on the base and could've easily been modified for a patch feed or just a "LNB" of sorts for my 10ft mesh dish. But it is either right under my nose here at the house or...

    The importance of knowing what your buying!

    I learned my lesson this past weekend, when I bought some antenna mount brackets to use for antenna mast mounts in the bed of my truck. I really didn't need the antenna to coax connectors, but they came with it. I thought it would be nice to have them in case another got damaged. Well I...

    A strange antenna question

    hoping this post will bring this old thread up to the top for a bit. I never found out what this antenna was for or what operating frequencies. Is that disk on top some sort of capacitance hat? Does it keep the signal dispersion low to earth for greater gain? I assume it is for either...

    CB co-phased antennas

    I said screw it as for the co-phased setup on the truck, I'll save that for my 10 meter setup with rotator when I get my 10m rig in the house. I opted for a 102" S. Steel whip. Of course I am thinking of a horizontal full wave co-phased setup for the 10m base.

    Will the FCC ever raise the legal Tx limit?

    Wow I love this site, so active and speedy replies, thanks all, very informative. As for the guy that said get my ticket, did you see my user name? lol I am a Tech class Ham and have dabbled in 2m, that's it, but my main interest is in HF and lower starting with 10m. All the interest in...

    can a higher power CB transmission cause damage to another rig closeby?

    For me I wouldn't run it with the gain knob higher than 1/4 the way up, just to be safe, that is if I knew for sure the other guy only had 4 watts with no amp. But I would imagine if the modulation pot was tuned all the way up you wouldn't need the gain up very high at all. As for damage at...

    Could a preamp be added to a CB?

    Could this preamp be used to increase the receive sensitivity of a CB? SA7 - Broadband Preamp Kit - Ramsey Electronics

    Will the FCC ever raise the legal Tx limit?

    Could they, or are there any problems that would arise from that? Even 10 watts would be awesome but 25w would be better. I know that having the proper setup and tuning the mod pot up can get you fairly decent range for 4 watts. But am I the only guy that wants more? I assume, knowing how...

    can a higher power CB transmission cause damage to another rig closeby?

    I remember when I had my Cobra 29 LTD Classic. It had the mod pot tuned at max and it spit out 25 watts, don't know if that info helps. But after I got it tuned I could hear folks on 4 watt rigs 12 miles south of the Interstate easily, and reach folks farther north of that highway. About a...
