Hi Guy

Looks good.. so you are on a hill too..have you noticed any effect facing up hill in directivity/ takeoff angle etc.?

What dimensions have you used? Ie tip to tip at widest point please?

I am using a homebrew LZ1AQ loop array with delay lines.. However quite curious about the mini k9ay setup..

Hi John and all

Have been playing with my directional lz1aq array.

First discovered one of loops was in operational.. that didnt help! Sorted now. Also played with delay line settings.

Getting circa 12-18db b/f ratio. ( with tx antennas detuned.) Sensitive enough to copy many Spanish and Portugal mw stations during daylight. ( from Devon.) tx antennas no copy/ very poor copy.

Issue is now noise in n/e direction.

This i suspect is due to top loop placed at top of garden, very close to neighbours house.

So as promising results am going to move loops down garden, thus moving away from noise source ( which by the way the tx antenna ( marconi t) does not hear.)
Also this will allow all loops to be at same height above gnd, at the moment one pair have circa 4m height difference, which also is not helping i suspect.
So now to acquire a scaf pole and 2 bags of postcrete.

Also if does work well to remake the delay line control box/ more loops to add 4 more directions, this is because the beam pattern is tighter than imagined. However this does depend upon my Wife allowing more antennas in garden/ antenna farm.

First to move loops and reevaluate.

?Hi John and all.

I have room for a dhdl, down the side of garden, would face north of east by abit and be reverseble. But would be REAL CLOSE to the tx antennas. ( though they can be isolated/ detuned , read lifted from gnd on rx if needed.?
But still would be on a slope and again below house at lowest level

Did try the big mag loop last night. Worse signals and same noise floor as the T. However will revisit tonight with the T isolated vis ptt on rx. ( was coupling to tx T, but was late and i had enough at that point. Had just laid 70m of coax to connect it in the dark.)Though not expecting much.

Also will revisit my lz1aq directional array with T isolated ( and mag loop detuned.)

I do have a yccc 9 element array to hand. All made, but no where to fit! ( house was looking at feel though.) which brings me onto below.

Also have room for a 4 square short active vertical setup, each 20m apart. BUT all verticals would be near trees, cables, tx antennas etc etc.. so a no go really.

There is another possibility. However..along shot..a directional array using 3 e probes..
Far end one at bottom of garden mounted on top of Marconi T end mast.
Others at equal height in a triangle formation. this would make them all above gnd level of base of house.
Would use redesigned Lz1aq delay line unit , or even the same unit but mod e probes to use cat 6 cable. However I can see that being alot of work for poor results. Though 4 directions.

Sigi

Look at the pi4cc antenna system..( re 3 inline phased.though they are verticals.)

i really ejoyed the video

i had never thought that two phased loops like the waller flag would have such high RDF number

(i use a k9ay loop here with not tooo bad results but was thinging about build a 2nd one and phase them)

waller flag seems to be fantastic ... (i can not deploy a 1000 feet beverage)

i also was thinking about building 3 loops in a row (cause i have trees in the right direction) and phase all three together but i have to figure out the phasing system ... and what i have seen in the video i maybe should just try two loops with one of them cross connected

Rather large, plus a fair few negative reviews..ie gone back to a k9.

I do have large mag loop at end of garden. ( total circumference 20m of no joins copper tubing.) My ex London qro loop..will try that outpointing towards Vk.. nothing to lose.

Hi Martin

I tend to agree with you. Even with 8 phased loops they will be “below” house gnd level in rhe direction interested in.
Would only be able to mount 1 on house roof level.

Next month am improving the T, the one 25m top wire is being replaced with 3. ( so will look like a mw tx antenna as used by broadcast stations.) This will allow less L on loading coil. “ every bit helps.” Last night worked a good few na and as ru stations on 160m using it..shouldnt complain really.

So unless someone has a plan for a small miracle rx antenna I guess will leave as is..( rx antennas here. Which are 3 crossed parallel loops, each loop made of 4 1m square loops, feeding lz1aq 5551 style preamps and a lz1aq designed 4 way directional delay line box. Thus giving me 2 phased inline loops in 4 directions at any one time.

A flag, k9ay, short vertical etc wont be any better due to where it would be mounted ( down the garden, near my tx antennas and they all appear to need to work against gnd or elevated radials, not practical on the roof!
