This final installment about the 6m LFA Yagi Antenna shows the technique to hold copper pipes to the boom using home center PVC plumbing materials.
Here is a step by step photo album showing how I prepared home center copper pipe for use in a three element Loop-Fed-Array Yagi-Uda antenna (aka LFA Yagi Antenna).
The Coplanar Loop Fed Array (LFA) Yagi-Uda design from G0KSC provides an excellent design foundation for an all copper version of a 3 element 6m balunless beam with superior front to back performance. Shown are comparisons between model simulations and prototype measurements.
The clever application of the folded dipole loop, computer science iteration techniques and NEC simulation to Yagi-Uda design results in a panoply of practical planar Loop Fed Array, LFA Yagi antenna recipes.
Is anyone else confused by the control some antenna designers try to maintain over the use of their unpatented creations?
G4CQM provides details on a Yagi-Uda coaxial dipole driver approach for designers lusting after a 50 ohm self-balancing feed.
Jim (K9YC) Brown’s toroid winding recipes provide a superb RF choke balun for 30-10m using RG316 and a #43 toroid.
Yet another 40m Cloud Burner design featuring a folded dipole driven element plus one reflector wire to facilitate 40m NVIS contacts without need of a tall mast. The design uses electric fence posts for support and needs no balun.
One example of how amateur radio provides safety and service to the pubic providing otherwise impossible communications using the “Magic Band.”
Even a 1B ARRL Field Day Station offers visitors a rare glimpse into Amateur Radio.
A Redskins fan uses Dallas Cowboys to further his pursuit of raising his hex beam to the sky.
Test results show coaxial cable velocity factor does not always enter into stub length calculations especially in the world of Baluns. Part 1 of 2.
