Cascadia dipole?

the antenna height makes perfect sense to me... common sense

 

Yes it does but not LoS, it has to do with the angle that the signal travels from the antenna.

If you want something to do, look up NVIS antenna. You can see where I am coming from.

 

Well dude..I see a small issue with that..I have a cpl times been able to hear as far as 20 miles but couldnt respond..That was in carlisle pa on I 81 goin s for about 20..Othet side was just another mobile..
So that curvature stuff i wouldnt take as gods word..
Always lots of other factors..


Rabbi...If i can tune my 10k but not the 5 ft there is something goin on somewhere..Cant tune the 7ft either..

 

sorry but on a crapcadia truck and a steel coiled antenna you want it above the roofline of that trk. but then I don't have these receive issues that most of these crapcadia drivers have. I also have a lot of grounding on my truck. the more grounding you can get on a crapcadia the better of you'll be. sorry but it is the worst truck to getting any decent results when it comes to anything.....

 

I'll do just that thanks

 

Do some research. 3MHz and below are the ground wave frequencies. 3 MHz and above are LOS frequencies. 3-30MHz CAN take advantage of ionospheric propogation - what you refer to as 'Skywaves'. Ionospheric propagation is random and unreliable. It's known colloquially as 'skip'.

Skywaves fall under the 'very special circumstances' that I mentioned in my post. Skywaves rarely affect radio wave propagation in a predictable manner. Skywaves are evident when the 'skip is running', in the vernacular of CB enthusiasts. Ham radio operators refer to this phenomenon as 'the band is open'. What Skywaves refer to is actually ionospheric propagation. And that only happens under very special circumstances, and is not reliable. It is, however, somewhat predictable, and follows the sunspot cycle.

Another special circumstance is known as 'knife edge propagation', which will allow communication beyond LOS when there is a ridgeline between the two stations that are communicating.

 

So bored....Without an amp what range are you getting on average

 

The other guy may not have been able to hear you because the noise level in his vicinity was drowning out your signal.

Power lines and other factors will create noise that overload the receiver front end amplifier. That makes it difficult to hear weaker stations.

I drive a natural gas truck which has a spark ignition system. That creates a LOT of noise in my receiver. So I can transmit with 4 Watts much further than I can receive.

 

Looked it up. Seems that NVIS antennas basically use brute force to create a band opening. You're basically hurling your signal straight up into an ionospheric disco ball and hoping that it makes it to a receiving antenna. In order to communicate, both stations need to be using NVIS antennas, and both need extremely favorable conditions.

I don't see this as being practical for the everyday mobile user.

Edit: It only works reliably up to 8MHz, and doesn't work at all above 30MHz. The CB band is 27MHz. Good luck.

 

Naw my set up needs something..Just dont know what..Something about how/where/what on my ant is set up to..
8 mi is my max and im not gonna be happy till i double that..
I know its not coax or radio or stud so its antenna is not right for my truck or something else..Cant get a 5' fibreglass (to short) or a 7ft ant.to tune..So that partly makes me think mount or what its mounted to..
I just need experienced eyes with hands on to find my mistakes..This stuff i keep reading from different sources is more confuseing that anything..
