CB and Amateur Radio Antenna System Evaluator


This JavaScript program evaluates the performance of your antenna system, computing the consequences of SWR and feedline loss. 73 de Ron JavaScript PROGRAM by N6ACH


original program concept done in CPM basic by KC6A and N6NB.

Antenna System
power from xmitter in wattswer from xmitter in watts -1VSWR @ xmitter 
feed line loss in db( must be in line with other values)  Enter 2.2 for dipoles; add 2.2 for antennas rated in dBd 
/* tells program what section to go to either "compute" or "reset" */


 

 


reverse power at xmitter -1VSWR @ antenna
forward power in watts at antenna reflected power in watts from the antenna
true power in watts into antenna power in watts lost in feed line
db line loss including EIRP in watts power in watts off the antenna
Coaxial Cable Loss in db per 100ft.
Frequency in Mhz

Trip 2002: Can you imagine loading up a van with 3 teenagers, 1 baby, 2 dogs and a husband and wife to travel halfway across the country? Do they survive? One of the teenagers has studied the Donner Party trip and she packed bbq sauce in her suitcase. One of the dogs is a ridgeback, to those who don't know, they are their own methane greenhouse gas ozone destroying machine. Follow along as we document this event.

The trip of 2003. To Washington, Alaska, Edmonton (with 2 teenage girls we had to stay at the mall;-), Yellowstone. What a road trip!

Dannex HF-Equipment

The road trip of 2004. OK, we did Alaska in 2003....what could we do to top that???? How about Florida! We drove to Fort Walton Beach Florida via Yuma, El Paso, Fort Worth, Baton Rouge, New Orleans, to Fort Walton Beach. We came home via Bowling Green, OKC, Amarillo, Flagstaff, Tonopah. Over 6000 miles, 16 states in 18 days. We are having too much fun.
