vinegar They are next door to me, I have used this stuff on cars and antenna stuff, incredible! (not cheap but worth every penny) Their web site is http://www.por15.com/ Yuri, K3BU List Sponsor: Cham
of and amazing thing, on the bay side of Cape Hatteras, there is hardly any tide or antenna destructive waves, so you get salt water without it detuning the (vertical) antennas. Love it there! Yuri K
Depends on wire type and dielectric. Using house wiring type, solid copper insulated #12 wire, the shortening factor is about 4%. Use solid bare wire in the software, then shorten the lengths by 4% w
I am in favor of 259 family too. (Only wish the foam wasn't' coming through the braid when soldering PL259 :-) I wonder if there is information on various dielectrics, insulators used for 259 family.
Sound like it got married :-) Last frying incident happened at VE1ZZ, who had brownish female on his antenna switch box and it just shorted out (with stink). Jack doesn't use connectors much, to join
That makes sense, confirms what I suspected and explains poor directivity of my triangular parasitic array using Stackmatch for switching driven elements. I am going to try simple relay swicthing of
How true! It is sitting at the computer, radio and wrong nutrition. I have been in that league myself, my blood pressure went up, cholesterol skyrocketed, "my" doctor kept me on medication, vegetaria
If you want it that way, than you have free birth control. If you want to have kids, just take a holiday for few weeks, time it with your wife's cycle and you should have no problem (if there is no o
Get off your butts and play with antennas and inspect the top of your tower every day. Replace that with kielbasa, cheese, nuts and club soda with lemon, you will last much longer, more alert and you
I have similar situation, in my case I have a split boom, so I can use smaller diameter insert for the rotor and then fit the both boom pieces over the insert and maintain concentricity. Another way
I sometimes use good quality rubber water hose in order to protect individual coax lines from underground or underwater elements. Find the right diameter water hose, slip it over the coax, seal the e
Interesting to see the variety of opinions on fixing that bend in the tower leg, from safemongers, to scaremongers, to lawyer solicitors. If it was my tower, I would make wooden form around the inju
If nervous, I would drill few holes in old concakrete base, insert some screws/rebars sticking out to new "base", set them in setting compound, use bonding compound between two concretes, and if stil
I finally got around setting up 10m 4 square (WPX SSB coming :-) and run into some problems. First I checked the ACB - 10 unit on the bench, loaded the 4 antenna ports with 50 ohm resistors, attached
I have tried that and have one working right now. If I set the individual radiators (3x) for 50 ohm impedance and run the array as 1 radiator with two stub tuned reflectors, the impedance is fine, 50
F/ you the Well, 10m unit behaves much differently than 160 and 80 ones I have, testing with noninductive resitors plugged right into the connectors. Never mind what is connected to the box. Coupler
<< You mention that your dipoles have an impedance of 110 ohms, so the 75 ohm 1/4 transformers are transforming this to 150 ohms. Not good, the hybrid coupler is looking for 50 ohms and I am sure Com

Thanks Tim, from the posts I gather that Comtek unit is looking for 50 ohm antennas, then transforms the impedances using 75 ohm quarter wave lines to 100 ohms, which are then paralleled to get back
Here we must be hitting on discrepancies between theory (modeling programs, some books) and reality. Using "crummy" 2 el. parasitic verticals and dysfunctional 3 el. triangular array sitting on the b
