Ideas for a homemade mobile antenna.
 
I have constructed a homeade antenna that is mounted on a trunk-lip mount on
a Nissan Sentra. The bottom is 18" of 1/2" copper pipe with a 3/8" theaded
adapter soldered in the bottom. There is a 9" long peice of pvc with a 2"
diameter 6ga. copper coil around it. Then there is 4" more copper pipe with
a 3ft' stainless tip on top. The problem is that it would be too easy to
bend the trunk with copper pipe. I thought about a spring but then the whole
thing would bend too much when the trunk is opened. If I move the coil down
below roof level, the SWR goes way up. I thought about using pvc for the
lower part but I can't quite figure out how to construct it. I may take some
pictures of what I have. Stay tuned......

Chris;

Nice home brewed antenna for the mobile. You are right about bending the
trunk lip with an antenna that size. Some people use guy wires, made out of
nylon rope or string, to take some of the forces off the antenna while
driving.

Most people use a form of bumper mount, or the trailer hitch. Either one
would let you construct a more robust mount for the antenna. Also I would
strongly suggest that you don't use regular lead-tin solder for any area
that you have to have high mechanical strength. It will crack I'll guarantee
you. You will have to use silver solder in its place.

Also try posting some messages on "rec.radio.amateur.antenna". They don't
care if you're a Ham, CBer, or what ever so long as you have an interest in
antennas. Some of those guys have already been down the road you're on and
can give you some VERY valuable tips on how to go about your project.

Good luck.

yes I agree you do nice work chris one question though the 6ga copper
coil and 1/2 in copper pipe are overkill for CB no need to go that big
unless you are running megawatts. Even with your illegal 100 w amp
you still only need a wilson or equivelent that would be much less
weight and problems. but may be you just like the look of it etc. the
heavy duty badass appearance kind of like car hood hold down pins on a
stock engine lol

Thanks. I just wanted to prove to myself that I could make my own antenna
and see how well it worked. There are 2 reasons for the large coil. In
comparing a few antennas of roughly equal length, the ones with large open
coils tend to be more broad-banded. Larger materials also have less
resistive loss and more radiating are. The lower part doesn't really have to
be 1/2' copper pipe but it was the first thing I thought of. I'm going with
copper wire wrapped on pvc shortly.

You don't have a clue to what you are talking about.

http://tinyurl.com/yq3gd

1) Broad Bandwidth does not mean an antenna is more efficient.


I didnt bring up bandwith someone else did

2) No one ever said a 4 ft antenna was more efficient than 9 ft one.


no you said the open air coils were more efficient

3) A 9 foot antenna "bent over" will more than likely be less
efficient than a properly designed 4 or 5 foot antenna.


the open air coil antenna is less efficient because the coil radiates
part of the power and that power is lost.

4) A stainless steel antenna is less efficient than a copper antenna
of the same length.


not if its electrically shorter than the stainless one

Now do you care to make another post and prove what a
stupid dumbass you are when it comes to antenna theory?

I would. What happens when you bring a solid sheet of conductive
material close to the end of a coil? Eddy currents -- it has
tremendous losses, the Q drops like a rock, and it's inductance is
unpredictable. It's a royal bitch to design a shielded IF/RF coil or
transformer to be used for high frequencies, and shielding is almost
-never- used for power RF coils and transformers unless there is some
serious space between the inductor and shield, hence the popularity of
toroid cores for those applications. And since a bigger coil makes a
bigger field, you need much more 'free space' to maintain a high-Q.
Vertically mounting a big coil above the sheet metal of a vehicle
results in a very lossy coil.



4) A stainless steel antenna is less efficient than a copper antenna

Electrically shorter? You meant physically shorter. I can take a 18
foot antenna and make it electrically shorter than 9 feet while still
keeping it 18 feet long. dumbass



The difference between copper and stainless steel is not very
significant at 27 MHz. What -is- significant is that bare copper will
quickly form a layer of corrosion (visible or not) which will render
an excellent conductor useless for RF. So unless you are willing to
polish and degrease the antenna every day, I'll take the stainless.

I would think that 4 feet would be more than enough distance.
So you would say that a large air wound coil has more loss than a
small diameter coild wound on a solid form?

It would depend on the diameter of the coil. I remember there is an
equation somewhere to determine the loss, but it involves some heavy
calculus and it's too early in the morning for integrals.


So you would say that a large air wound coil has more loss than a
small diameter coild wound on a solid form?



No, not necessarily. If the wire diameter is the same, the smaller
coil might easily be more efficient due to lower DC resistance.
Distributed capacitance isn't much of an issue at 27 MHz unless you
have lots of close-wound turns, and even then it's not necessarily a
loss but a factor that affects the coil's reactance. Regardless, there
are very effective winding techniques to reduce that problem. There
are many low-loss coil form materials available, such as Teflon, some
of the better quality ceramics, and even grooved hardwood makes a
decent core at RF frequencies (however, PVC sucks above a couple
hundred kHz). There is also the issue of weather conditions that can
significantly affect an open coil regardless of whether or not the
wire is insulated -- rain/humidity, snow, air pollutants (ozone can
make a -=BIG=- difference!), etc. Even the speed of the vehicle can
have an effect on the properties of an open coil. For the sake of
consistency and longevity, a smaller coil that is sealed from the
elements (as a whole) is a far better choice for anyone serious about
the issue.

BP. He defends Doug a known Felon, repeater jammer,
porn poster, spammer, nut case. Leland defends Doug too,
so George has no legs to stand on when calling other people
hypocrites.

I would think that 4 feet would be more than enough distance.
So you would say that a large air wound coil has more loss than a
small diameter coild wound on a solid form?


There are no large coil cb antennas where the coil is 4' from the vehicle
roof, they are all mounted 18" or less.


Bug Catchers aren't.. so all isn't correct.

Replacing the lower section with pvc for flexibility. Sorry this thread is
hard to follow....too much off topic content.

be 1/2' copper pipe but it was the first thing I thought of. I'm going

with
copper wire wrapped on pvc shortly.

Chris; Nice looking antenna, large open air coils are more efficient.
Some people see a large open air coil and think its all about power
handling capability. Are you planning on replacing the coil with pvc
wrapped with wire, or the lower section? If you want to beef up the
lower secton you might take a trip to a hamfest and pick up a lower
section of a Newtronics Hustler.

Chris; yes there is, and for that I apologize.

PVC gets very brittle when exposed to sun or cold. You might need to
think about hooking some kind of line to it keep from losing the top
of the antenna in case it breaks.

Frank and Hall and both ran to defend N8WWM on many occasions, too. This
little group is what comprises the "akc" that Frank always refers. Hell,
"AKC" is one of Frank's favorite terms,,google THAT term and see who
pioneered it,,,Doug, Frank, Lelnad, Geogre, and Hall..in that order.

rotflmao I dont think mounting 8 lb. of plumbing on your trunk lid is
efficient. There are easier ways to get bandwith. for example if you
want efficient youd be using a 9 ft whip. even bent over like a bow
the 9 ft is more efficient than a 4 ft loaded open air coil model.


Huh......... A bent over 9 foot whip has a very noticeable Loss
compared to a efficient 4 or 5 foot vertical.

Hey Jay, what do you think about this antenna, and any news
on the 10K mobile yet?

Many times...........even tested them.

Sorry your tests results were debunked by Frank in the xterminator

Not speaking for them just stating a fact Tnoms antenna tests were
shown for what they are which is voodou cb science.

Bull tweety..call the google line and punch in

Report back with your findings, google-****.
