Hi folks, I have four kits purchased on ebay for receive antennas as well as a bi-directional beverage from KD9SV. Looking on my county plot map it looks like I can run about a 412' beverage using my
Terry My tower is 116 high , plus 10 ft of mast with a top hat, and the HWF. I never had any problem on 80m because the antenna is too long and near 1/2 wave vertical for 80m, my Vertical WF is 60 ft
On 160 I've used a vertical wire of 20 feet with a 1000 pF variable capacitor to detune a tower at its base. You can scale that to 80. 73, John W1FV Hi again, This may not be possible to answer with
Hi again, This may not be possible to answer with anything like 10% accuracy but can someone give me an idea just how much capacitance I need for putting up a 50-55' vertical wire up the lower half o

Folks, Thanks for the off & on-line replies. There were all positive replies to doing it, nobody mentioned issues with harmonics. All the antennas are in different directions, none run parallel to ea
There were quite a few good openings this season. We took down our E/W slopers just before CQWW CW and replaced them with 2 top loaded phased verticals (vertical height about 30m). The new antenna se

Good Luck George....I was the 160 op with the 1969 operation and worked several hundred on TB with a wire suspended above the water on the cliffs protruding across Lulu Bay. I had hopes of hanging sl
A Delta Loop is probably the least noisy of anything you can hang off an AM tower. I tired both slopers and a Delta Loop here (corner fed) and there and the noise was significantly lower on the Delta
Tom, Let's revisit Jaan's original question: Background: I have a tower that is 137ft. or 42m tall. It is triangular 1ft 10inches or 40cm wide. The tower is guy wired at three levels with non-isolate
I think I would hang a delta loop off of that tower. It would be very slightly squashed. You would not have to worry about matching the tower or installing a radial system. Through in about a db of g
Or an easy and fairly good approach is to set up a sloper off the tower. The sloper acts as an inverted vertical ( inverted verticals work better than ground fed ones) and uses the grounded tower as
Perhaps so - but Dale is gong down there to put in a 240' broadcast tower. 73, Charlie, K4OTV I agree with Herb. Also Haiti is on an earthquake fault. The quarter wave tower would have a better chanc
I agree with Herb. Also Haiti is on an earthquake fault. The quarter wave tower would have a better chance of survival and is safer. 73 Bruce-K1FZ Half wave verticals have been very disappointing to
Half wave verticals have been very disappointing to me over the years when I had the tall BC towers in my backyard to play with after midnight on 160. I have had much better result in hanging 1/2 wav
Hi all! Been a member of the list for years. RX antennas are four elevated EWEs rotatable from a switch in my shack. I am contemplating replacing Alpha Delta DXA slopers, hanging from the top tolt of
The interaction of a grounded steel tower, I have found, can be minimized somewhat by having the end of the 80 meter antenna more than 25' away from the structure and supported with non conducting ma
Interesting. I have tried verticals, slopers, inverted V's and other 80 meter antennas on or near my 160 meter tower with little success. The impedance of any such antenna seems to be severely altere
