 |
|
The amount of archived data on antennas is overwhelming and some of it more technical than I can follow. The volume of this data possibly suggests the amount of not easily solved problems with antennas. I thought I had come to an installation solution that would bypass most if not all the potential problems until I read that some are having trim servo interference problems with the comm antenna. I had intended to install the Archer "v" configuration antenna in the fin and a second "s" configuration comm antenna on the fuse side rear of the baggage compartment. The Archer information says inside the fin is the ideal place for a glass plane considering it needs to be placed in a vertical plane. My transponder antenna is to be on the rear fuse bottom side, reasonably far away from the cockpit.
Has anyone installed an Archer comm antenna in the fin without having to shield the trim servo and its wiring? I intend to follow Archer's instructions using proper shielded cable and also staying as far as possible from other vertical metal objects and mindful of establishing adequate grounding for each component.
As I am trying to bypass the complexities of antenna installation and theory, any input/help would be appreciated.
Thanks,
Bill McClellan

Hi Bill.
Most of this antenna data, including the technical stuff has as sole purpose to confuse and sell a piece of material worth 5 cents for 150 $.
Fact is, that the antenna should not be very good, otherwise it would not work good enough over the whole bandwith. Interference (on reception) from on board equipment is not caused by the antenna, but by interfering equipment or its wiring Really, the 20 cents piece of copper to be cut and glued as an antenna, as supplied with the kit works just fine. Actually better then the 175 $ certified piece of aluninum on the club cessna 
There is so much more effect to be gained by spending the extra money on real improvements!

Jos Okhuijsen

Could not agree more. The factory copper strip in the sternpost has always
worked brilliantly in G-JULZ. Spend your money on something useful.
Regards,
Mike

Hi Bill,
I installed the Bob Archer in the fin. I have some photos but haven't had a chance to upload them to my album yet. Let me know if you need some and I'll send direct. Steve Hagar in Mesa used the same installation and reports good results.

I installed the Bob Archer "Big E" toward the rear of the fuse, on the
port side. Always had great reception...

Hi Bill
I have the normal Europa copper tape Di-pole on the stern post and a Bob Archer Just behind the D panel Port side, To be Honest the Copper tape antenna works much better, Have read ATIS at over 70NM with a Xcom and about 50NM with the Garmin SL30 using the Bob Archers,
regards
Ivor

I think the various comments made on this subject shows that the
installation is probably more important than the choice of product.
There have been many positive and negative comments about each type of
antenna. Quality of the connections and avoiding tight bends in the
cable are important considerations.
I am considering putting a second antenna into the fuselage to enable my
handheld to be used as a backup radio. Handheld radios will work well in
the aircraft provided they have a proper antenna. The short rubber
antennas give poor transmission and are useless for a touring flight
such as a crossing of the English Channel.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> Good comment Nigel,
I have installed all three but prefer the carbon fiber Advanced Aircraft Electronics (AAE) antenna types because they are "no brainers".
Hook an AAE to your handheld and it is a great backup for anyone. Heck, just tack with super glue in spots between the epoxy aft of the area behind the bulkhead for a quick retrofit. Use it for your ELT also if you want instead of rigging a ground plane.
I can hook my "Sporties SP200 to the AAE antenna and it is as good as the Narco.
If you need to make an antenna, by all means get an VSWR meter and tune it to make it perfect. It is only a few dollars but time and tuning is spent also. Personally, the older I get, time is a precious commodity.

Nigel-
What Alan says about the AAE antenna is dead on. It is a folded diploe, as opposed to a dipole, therefore the bandwidth is about twice that for a given SWR as a dipole. In addition to the AAE in the rudder, I have a second antenna installed just aft of my baggage bay. I used 1/16 plywood, 3/4 inch wide, covered with 2 plys of BID and extended it from the floor to the celinig just aft of the "D" bracket, with another piece about 8 inches long going from the middle of that piece to the aircraft skin about on the line between the upper and lower canoes. Copper stripping is fastened to it and center fed with RG58U. The ends are bent, the top across the top of the roof, the lower along the floor for about 6 inches. This doesn't matter much, the most critical part of a dipole is the center portion, the further out you get, the less sensitive it is to bends and distortions in the tape. You can easily tune it using an SWR bridge. The AAE antenna does not need to be tuned; if fact, if you attempt to tune it, you will destroy it. My second antenna was installed for amateur use at around 144 MHZ. The tape is a very inexpensive and very effective answer for the comm antennas, but the AAE is a good choice for permanent installation in the tail.
