I agree the HOFI HOSCHA remote switch is great. We sold a dozen back in the early and mid 1990's at Electronic Switch. Mr. HOFI is hard to deal with so you must get them direct. He did have a web pag

Both the KLM 5 El 20 and 6 el 20 were called "Big Stick" originally. The 5 el is on a 42 foot boom and the 6 el is on a 57 foot boom. I had the 5 el 20 in the late 1970'S. 73 Dave K4JRB

Two of the best verticals for 160/80/40 are no longer made. The Uni-Hat CTSVR was reviewed by Lew McCoy and is in his last antenna book. The Gladiator line of Low band verticals also went out of busi

An alternative to the G5RV for an 80 meter antenna to fit in 100 feet is the Carolina Beam 80 which is a partly a modified G5RV and a Carolina Windom. This antenna works more like a SCV as described

Remember that a 4 square is only a 2 el vertical array with the ability to put out a uni-directional pattern in different directions. A vertical is down 2 or 3 DB from a half wave dipole at one half

My T2X is sticking and at times will not rotate so its getting to be time to repair or look at replacements. Does anyone have experience with the HD-1800 from CATS? Their web page says I can use my c

The question was asked........ A I have the same problem with my 33 year old 71 foot crank up. I found that the Prelub 6 product that K7LXC sells works well in conjunction with a soap scrub brush. Ju

I agree with N2EA that hams outside New York should not comment on the Tower Bill. I have been to meetings on towers in different counties and the politicians get annoyed at what they call outsiders.

Steve, I use the old collins balun made from 10 loops of coax on my older 402CD. Maybe going this route might help. I do remember K5UR's story of the flare on his tower when operating the 160 Contest

I feel that 468/f is just a beginning point. Look at the derived formulas for directors and reflectors in multi element beams. I found that the MULTEE antenna shown in both the ARRL and W6SAI Handboo

The best Field Day antenna I have ever used was a Hornet (later Swan Hornet) 2 el 40 meter beam. The antenna looked like a 2 el 20 meter ith 36 foot elements and short boom (maybe 16 feet). The Horne

There is some confusion on the W9INN antennas. The antenna labeled "Broadband" has two flavors. There is a 160/80 version and a 160/80/40 version. This antenna does not require a tower to complete th

I heard a W6 talking on 17 meters today and he said he had 5 towers on his 1/3 acre lot (with house in the middle). Boy, I'll bet the self created intermod must be terrible! Wonder how close they are

For a low horizontal loop you can wind it through trees (I use #12 black plastic wire that comes in 500 feet rolls from Home Depot and less than $20). If not there is no reason why it can't be hung f

I seem to remember the rotatable dipole is about 60 feet long so there may be interaction between the element and the 40 meter beam. Perhaps some type of stub detuning of the 80 meter might solve the
