- I started putting together one of your portable flag antennas. Regarding the resistor that is used by notice its called out as a non-inductive resistor. Is this something special or with a standard c

- Typically carbon resistors are non-inductive in the HF region. Lower values of modern film resistors usually are pretty good, also, in that respect. Film resistors may be laser trimmed for the tighte

- Hi Bob, Dave (W0LEV) provided you good insight. Normally I say just stay away from wire wound resistors as we know they are definitely inductive, and carbon resistors are just fine. Any value of term

- Hi Dave, I have not but I believe it should work (especially since a diamond works). You can look at other configurations that are known to work by reading the original article about Pennant and Flag

- Cool... I am thinking of comparing it to a Mag loop. I am setting up a RX only antenna for my K4, and suspect the cardioid pattern will do far better than the pattern from a mag loop. Half the noise.

- NB., I had excellent results in the past with a half-size K9AY loop, only about 12 ft high, vs the normal 25 ft or so as seen depicted on websites and in the literature. At this size, its also 'good'

- Hi Dave, You wont yield half the noise, and its a complicated topic but I suggest you read up on whats called RDF (receiving directivity Factor) and this was a concept that I believe W8JI first intro

- Thanks Don!! I will read up on that... I am thinking the flag will work better as it does not have lobes in two directions, like the loop... That way, I can null my RFI source better. I have only one
