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.
JavaScript PROGRAM by N6ACH


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

as of 3/21/15 working on adding rf safety calculations from a N6NB basic program.


forward power from transmitter in watts -1VSWR @ transmitter
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 
Enter operating frequency in mHz 1.8mHz to 2450mHz




reverse power at transmitter -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
