As a new K2 and antenna system loom in the near future (K2 is in transit), I am working on the design and modeling the new antenna. This will be very simple, an 80 metre doublet feed with homemade open wire feeder. I will use the antenna on all bands 160 to 10 meters. I will also tie the feeder together and feed against ground for 160 meters, and possible higher bands.
The antenna system will be tuned with a KAT100 and connected in it's balanced doublet configuration with a BL1 balun. I would like to put some sort of bleeder system from each side of the open wire feeder to ground to bleed off the static electricity. I have four 2 watt 1 megaohm resistors that I was thinking of using, two in parallel on each side of the feed line to ground. The resistors are made by NTE and are metal with a voltage rating of 500 volts. Specs at http://www.nteinc.com/resistor_web/pdf/twow.pdf. Will the resistors be a good solution or would a proper RF choke be a better idea? Can an RF choke be built that will work well with the K2/100 and KAT100 and not cause additional problems with resonances, etc. Also what will happen when the two RF chokes are connected in parallel when the feeder is tied together for 160 metres? Will I need to disconnect one of the RF chokes?
