A question about HF radio and antennas?
This question is about CB radio….but i could use some help from hams who use 10 meters for broadcasting also (the same physics pretty much apply)…..so i have a question about the range of a CB radio……i live in a place thats pretty flat and heavily wooded……I was wondering which antenna design will give me the most range out of my 4 watt transceiver…..The first design is a loaded 4 foot monopole mounted in my attic (keep in mind that my attics height is above most of the surrounding terrain and abstructions….also my attic has no wires or pipes in the ceiling and has thin walls)…..i know the attic walls will attenuate my signal slightly………the second design is the same antenna mounted on the ground (12 feet below my attic level) with a extensive system of below-ground radials…..so which one is better?
sorry about poor grammar
as a general rule, the higher the better – so in the attic may be the better of your choices because the attic has relatively few restrictions
now hopefully, this 4′ antenna is a ‘marine’ or ‘no ground plane needed’ antenna – else you will need a groundplane (counterpoise) for the antenna to operate correctly
how about putting the antenna in the attic and putting radials on it there ?
These waves are in the field
Sometimes a public park is the best place to crank up a radio.
Antenna guru: ‘Get a bumper and learn the Vulcan iPhone Pinch’
“The public will be more ‘antenna-aware’: that’s the good thing to come out of this. They’ll walk into an AT&T store and say ‘lemme see that pink phone and what kind of antenna does it have?’ That hasn’t happened since we bragged about our newest rabbit-ears [antenna] for our old TV sets.”
10 points! where can i find an extension av cord for my xbox 360?
we got our flat screen mounted on the wall…but the AV extension cord is not long enough to fit to our media center where the xbox is. do you know where i can get a connector for it? please let me know what website. thanks!

Learning about Subframe Connectors
To new muscle car owners going to the drag strip for the first time, quarter mile runs are usually seen from a single point of view: horsepower. A lot of dudes out there think that the more horsepower you have got, the faster you can go, plain and straightforward. Of course, over time, if they stick with the sport most drivers come to realize that there are actually a number of different factors that come into play when trying to get your car down the 1320 as fast as possible.
Power might be important, but the more power you have, the more control you are going to need. When you are ready to get serious about drag racing, that means it is time to start researching about suspension and chassis development, and how that can affect the ability of your muscle car to put power down to the ground and effectively launch down the track. All the horsepower in the world is not going to help you if you just sit there at the starting line spinning your tires.
Once you have gotten your suspension setup all planned out, and chosen the right type of tires to mount to your car, you might still be looking for an extra edge when it comes to keeping your horsepower under control. Have you ever noticed how some of the high-horsepower drag racers lined up at the track seem to have a staggered ride height that lifts one side of the car up higher than the other? This is to counter the twisting of the chassis that occurs when a huge amount of torque is released all at once. This chassis movement can be a serious impediment to traction, as it can lift the rear wheels off of the ground and cause them to hop and skitter, slowing you down and possibly causing damage to your diff.
Now, you probably do not want to end up having your street-driven hot rod looking like some Frankensteins monster with a bizarre suspension that you have to explain to everyone you meet. Fortunately, there is an alternative that is more than capable of handling daily-driver levels of power and chassis flex. By implementing components called subframe connectors, you can keep twisting to a minimum.
How do subframe connectors work? These small plates of steel bolt or weld onto areas of your cars frame in order to provide extra stiffness against the rotational force of your car’s torque. There are quite a few different types of subframe connectors some of them are simple to install, while others require you to tear out your floor and do some heavy welding. Ultimately, the type you will need will be determined by the original strength of your cars chassis, and the level of horsepower that you are running.
Subframe connectors can be a great way to get even more out of your ride by harnessing the horsepower that you are already generating and putting it to better use. It can also help tighten up your car for the street, giving it slightly better handling and smooth power delivery.
