Titanex DLP18 HF Log Periodic Reviews: 2 Average rating: 5.0/5 MSRP: $1489 Euro
Description: 18 Element Wire Log-Periodic 7MHz - 30MHz
Very low wind load: 600N (at 120km/h)
Low Weight: 24kg (52.8lb.)
Optically very inconspicuous appearance through the use of wire elements
No swinging elements at strong wind
Power handling: 5kW PEP
No balun necessary
Double-boom (60/18mm), electrically fed = increased gain
High number of elements due to wire stringing
No corroding parts through the use of special stainless steel clamps
Best low angle radiation through high number of elements
Crossing-free feeding of all elements with a defined impedance
Feeding with just a single coax cable for all seven bands (50 Ohm)
Loss-free linear loading feeding on 10MHz, full-size rotary dipole on 7MHz
Suppression of strong BC transmitters in the 7-13MHz range because 7 and 10MHz are designed as skip-frequencies (resonant bands)
Boom length: 10m (32.8ft.)
Longest element: 10.42m (34.1ft.)
Turning radius: 6.1m (20ft.)
Gain: 14-30MHz: 7dBd, 7MHz: 1dBd, 10MHz: 2dBd
Front-to-back ratio: 20-25dB from 14-30MHz
VSWR: typically 2:1 and better on the amateur radio bands
Product is in production.

10 Years with good performance  Time owned: more than 12 months
After I have diminished the aerial the last week after 10 years I would like to deliver a final report.

The aerial has shown, up to the missing ceramic insulators for the 30m-band, no problems at all.

No corrosion has appeared and the plastic ropes would have held absolutely still some years.

It is really a good aerial and can show the advantages to cover all 7 amateur tapes of course best of all when it is built up very high above ground.

So, after 10 years it is still rating 5/5 !

7 bands on one coax, 5 with directivity†  Time owned: more than 12 months
The DLP18 is a fine antenna and works great once itís assembled right.
It is delivered as a puzzle of a few hundred eaces.
The assembly instructions were full of errors.
Most of them should be corrected now (after several telephone contacts and
a personal meeting at HAMRADIO in Friedrichshafen).

Itís in use for more than 2 years now.
I put the antenna at 26m above ground to make use of all bands.
At this height the best thing is that you get all bands from 10m through 40m radiating with low elevation angle best for DX.

Mechanical construction is OK with respect to wind-survival, no problems so far.
At the 30 meter element the rope burned down once and the dipole dropped to earth. I had to repair this by placing egg-type isolators.

If you assemble it once, put it up there and leave it, it might deserve a rating of 5.
