I have a FULL range Shortwave Radio and I would like to get Australia in.
I do not know what Meter Band they are on or any of there FREQ. there are on.
And what would be a good time for me to try to get them on my Radio.
I am in the U.S.A please help.
Thanks
Need help
Ok thanks for help I now know how to findout how long to cut my ANT wire for a given FREQ.
But what if you want to make an ANT for not just one or two FREQ. but for the whole Shortwave Spectrum what is the Math for that?
I now know if you know the FREQ you want to get you Divide...
I need help findingout the wavelength to get the Length of wire for an ANT.
I think it goes like this.
300 Divided by FREQ in MHZ will give you the Wavelength in Meters.
So if I wanted to cut an ANT. wire to get the FREQ. 7.05 MHz it will go like this.
300 Divided by 7.05 MHz = 42.55 Meters...
Coaxle help
OK I will split the Coaxle Cable myself and make it all like that.
But what if I use a Long Wip ANT. and just take the 300 Ohm wire from it and connect it to a 75 Ohm Coupler.
Will this work or why would this not work just thinking???
ANT help
I just called Radio Shak and told them I needed
a PL-259 connector to go onto a Coaxle Cable. And that will go onto a SO-239 connector.
And the SO-239 connector will give me Left and Right Taps. And I told them I need it to give me the Center Pin for one ANT Arm and the Outer...
I have called every Radio store and Electronics store and even on the net.
I can't find the PL-259 and the SO-239 connectors and every place tells me they don't know what they are.
I am going to put the PL-259 on one end of a Coaxle Cable and the PL=259 will connect to the SO-239 connector...
Coaxle feed
OK ok I am sorry I don't think I told you it right.
I am going to use a Coaxle Cable just as a feed Line to go from my ANT. to my Shortwave Radio.
And I am going to use just Wire for the Left side and Right side of the ANT Arms.
Now what I need is this?
When I use the Coaxle...
I thought that a Balanced ant. was when the one Coaxle Cable connected to eatch side of the ant. Then came to a center point and whent to the radio????????????????????
I was readding about Un Balanenced and Balanced ANT on the net and I wanted to know if I unstand it right?
A Dypole ANT has Left and Right ANT Arms.
Now coming from the Left Arm will be a Coaxle Cable and coming from the Right Arm will be a Coaxle Cable.
And the Two Cables will connect in...
Thanks for ant help
Ok I am not going to use a Balun for making my ANT.
OK this is what I think. I don't want a FREQ depanded Balun I would like my ANT to work as well as it can on all FREQ.
So this is it my Radio takes an 8th of an inch Jack and I know what kind of Connector I need to get...
balun help
So a turns Balancet to Unbalancet ANT or what is that for??
I looked on the net and found something about a Balun is a device for turning a Balanced ANT to Unbalancet.
A Dipole ANT is Balanced so I would not use this RIGHT.
Or am I getting miss information and not understanding...
OK I know how to do this kind of ANT by hand.
But if I don't want to hand cut the Coaxel cable into the Left and Right sides I wanted to know of a Device I could just connect the Cable to and it would give me two Taps for the Left and Right.
Someone did post the name of one but I can not...
Please help
Can I use a
so-239 chassis connector
It looks like you just screew the Coaxel Cable onto one end and there are two screews for connecting Left and Right Leads to.
Is this ok??
If Not please give me the name of the Part I need and maybe ware to get it I can't find any parts...
I am going to make a Diepole ANT and it will have a Coaxel Cable as the feed Line.
So I know you can just Strip the Cable into it's two halfs. The center pin will be for the one side of the ANT. And the Outer Shield will be for the other end of the ANT.
But intead of me doing it all by hand...
I think I am getting a little mixed up here??
You did tell me 468 divided by FREQ in MHZ = Length of wire in FEET and then I just cut that in two to get the left and right lengths of wire for my ANT.?????
And is 18 Gauge wire ok??
Soory just tell me these 2. things
freq help
So do I have it now 468 Divided by FREQ. in MHZ gives the length of wire in FEET then I just cut that in half and that will give me the left and right sides of my ANT???
tneed some more help
468 Divided by FREQ. in MHz = Length of wire in FEET then take that and cut it in halfe and that will make the two ends left and right???
And what is the 468 stand for??
Thanks for all the help
