Modified 160m RX Arrya season 2015/2016
QTH is 4km from here via Remotering.com,antennaswitches and icom ic706 with smal cw filters
Now using Beverages 200m ore more open end ore endfired...Baluns in use are from Hari-Ham...location is on the farmland ..vy low noisfloor...
as support pol i use gfk pols from nato masts some 1,3m long, what are fixed and hammerd in the ground in some alutubes about 50cm long
Here some pictures:
200m 0-180 degrees uni (Can be terminated if needed)
250m 120-300 degrees (Can be terminated if needed)
300m 80-260 degrees (Can be terminated if needed)

Up to now my experience with TX Antennas from Expeditions and from my Home Qth are the following: |
This is a small low noise receiving antenna for those without adequate room for beverage type antennas. A pair of side-by-side 150 to 300ft spaced Pennants are close to a 1000ft beverage in performance for DX reception.
Antenna can be mounted so that bottom is approx 6ft above the ground. No ground system is required for this type of antenna. Two side-by-side Pennant antennas can be separated 150 ft to 300ft and fed thru equal lengths of coax. 150 ft spacing works well for both 80 and 160 meters. 300ft spacing gives a beamwidth of approx 55 degrees on 160 meters. 150ft spacing on 80 meters has same pattern as 300ft on 160 Termination resistor from 820 ohms to 1000 ohms is adequate. Front-to-back null is approx 30db for this resistance range. 910 ohms is a good mean value. A Pre-amp having about 20db of gain is necessary on 160 meters. 10db or more is adequate for 80 meters. |
