Personally I chose to use the PAC Wireless 28db parabolic because they provide a substantial amount of gain without too much aperture size, a 6' dish isn't fun to deal with high on a tower.
I have had excellent results using the PW 28db parabolic on links in excess of 18 miles LOS at -60 with throughput averages of 48Mbps faithfully.
The XR5 coupled with the PW parabolic works very well also IMHO, lots of head-room and I find that they deal well when there are other 5.8Ghz gear from other operators near your Freqs too
I won't say anything negative regarding the HL 32db's, however, as with anything, too much of some things are not always the best scenario or solution.
Another thing is that you will in most cases find that the higher the gain factor the narrower the beam-width, while narrow beam-width is the way to go- you must remember that you will need to have a person at each link point to fine-tune the parabolic for the best possible S/N ratios.
Your partner will need to make minute adjustments while you watch your readings and then vice-versa for yourself making adjustments while your partner watches his end.
When tuning a parabolic it is always best to start with each reflector setting at negative Elevation and work into the sweet-spot beginning with the Azimuth first.
You can find yourself sitting in the side-lobe of the antenna's radiation pattern thinking you have the best possible signal, but don't stop there, keep tuning your Azimuth to the max in each direction until you absolutely validate that you are in the sweet-spot of the reflector.
Only once you and your partner have validated that each antenna is near bore-sited is when you would begin the fine-tuning in Elevation.
I'm sure you have already devised something as I am going to suggest here also Expunge- get a-hold of some structural aluminum tubing which is 1-1/4" in diameter, I located some old hang-glider tubing.
Cut the tubing long enough so it can protrude the outside of the tower at least 1-1/2', then cut a slot in one end of the tubing wide enough to receive the lattice in your tower and create a hook-point.
After your slot is completed drill a 5/16" hole clear through the tubing a couple inches from the slot you cut earlier, this is where you will use a hardened 5/16" bolt and nut assembly in conjunction with a length of heavy chain which will basically wrap around the back tower leg next to where the slot is receiving the lattice keeping it from just pulling free with weight applied.
Make sure and use a double-nut on the bolt so when you are hooking to the tower you don't have to worry about losing the anchor chain bolt, then you just remove one nut by hand and warp the chain around the tower tube then onto the bolt then just place the nut finger-tight
On the opposite end of the tubing you will drill another 5/16" hole and another slot will enable that end to receive a pulley which is to be rated to at least 200lbs and can receive from 3/16 to 7/16" climbing rope.
At one end of the climbing rope secure a snap hook capable also of at least 200lbs, this will be used to secure the aperture for the lift process.
Once completed when you set the hoist onto the tower the slotted receiver end with the chain will secure the back side and the opposite end will be supported by the tower lattice on the pulley end.
Now your partner can fasten the aperture using the snap ring and then pull it up to you easy as can be, once lifted into place your partner can tie off the rope at the bottom so you can safely install the antenna to the tower.
It's interesting reading through the forum how many people in the US are experiencing so many issues with other WISPs way beyond power limits or saturating the spectrum with poorly designed installations and making it a nightmare for everyone. I guess that's the price one pays with Part 15 gear and ISM bands
Isn't that the truth!
I have two other operators in my area... one guy has had his system going for 3 years and can't seem to figure out why his clients can't connect reliably, he actually doesn't even bill his clients due to poor connection.
This poor guy is too meek in my opinion, I spoke with him regarding the issue at-hand and suggested he have a sit-down with the other guy but he doesn't like confrontation and chooses to suffer.
Me on the other hand; I love confrontation!
I have called the offender in our area to the table on more than one occasion but my requests go unanswered.
I know this guy is doing this on purpose too!
When I first found him to be the problem the noise floor was -80, now he has upped the anti and the average 2.4Ghz noise floor stands at roughly -64 presently.
This guy has been in biz in our area for a little over 4 years now and doesn't like competition!
When we first turned our towers up in 2.4Ghz my answer machine was barraged by the offenders calls begging me to change frequency and his final call sickened me as he sounded like he was going to cry.
He uses channel 11 in one valley and totally walks on the other 10 channels due to over-amplification coupled with omni antennae.
This guy I guess believes in brute force and kill thy competitor with unusable spectrum.
The offender of my area purposely avoids all forms of contact with me.
He's not only ruining the business aspect for others but also making problems for himself as he has created so much noise in the valley that it is now working against him and his clients also.
Considering the fact that I continually take calls from his clients complaining of no connectivity when they need it and his failure to return their calls for support work into my favor as I convert a large number of his clients over to my system regularly.
Good luck on your venture at either rate Expunge, I hope to hear your success story regardless of hardware options you choose to go with.
